DEAR ABBY: I'll get right to the point. I have fallen in love with my sister's boyfriend and he with me, so he says. We have been lovers from the first moment we realized our feelings for each other were mutual, and have been hiding them from my sister ever since.

"Greg" is not only handsome, but he listens to whatever I say, takes it into thoughtful consideration and gives me honest feedback. I have tried to let him go and found it quite impossible. He is the most precious thing in my life and he has my whole heart.

Since this has been going on, I have become more and more confused about how I should act, what I should say and do. However, my love for Greg grows. I don't want to hurt my sister, but we were never very close to begin with. Is this relationship worth my pain and great love? -- LITTLE SISTER IN NEW HAMPSHIRE

DEAR LITTLE SISTER: Let's get right to the point. The man you have fallen in love with lacks integrity. He is your sister's boyfriend, and he's juggling both of you. The longer the sneaking around continues, the greater your chances that it will be discovered. And when it is, it will cause a rift in your family and Greg will head for the hills. My advice to you is to end it NOW.

DEAR ABBY: Often, when I have a dental appointment, it will be scheduled in the late morning -- around 10 or 11. I think it would be terrible manners to eat before going, and have the dentist dig through the food in my teeth.

After the actual cleaning and then following the instruction of waiting before the next meal, it could be as late as 1 p.m. in the afternoon before I get my first meal of the day. Some people have good stamina, I suppose, but it is very hard for me to wait that long.

Have you any suggestions about how not to go hungry and yet not be rude to the dentist? -- CLEAN TEETH, RUMBLING TUMMY

DEAR C.T.R.T.: Enjoy a nourishing breakfast and then thoroughly brush and floss your teeth afterward. If you will be eating out, take along one of those little travel brushes and mini-toothpastes that are sold at markets and drugstores everywhere. That way you won't be hungry, and your dentist won't be grossed out.

DEAR ABBY: The letters you have printed recently about cute comments made by children reminded me of something that happened with my son a while back. My child was a preemie who later developed a condition similar to a hernia. It's common in premature babies.

When he was 3 years old, I took him to a pediatric surgeon to have the condition corrected. (This is when the problem began to manifest itself.) My son was given the typical examination by the doctor for a hernia. At 3, my son stood on the examination table, and, as the doctor examined his testicles, he shouted, "I'm going to tell an adult!"

The doctor looked at me as if I should do something. I told my son, "It's OK, Mommy's here, and this is a doctor examining you, but in any other circumstances, you do exactly what you just did!" The doctor didn't say a word, and I gave myself a silent, "Yes! He understands!"

Kids need to know. -- KAREN IN TAMPA, FLA.

DEAR KAREN: I agree. And bravo to you for making sure your son understood that important lesson early.

DEAR ABBY: I recently began dating again as a single mother. I met a man I'll call "Mickey" at a singles dance and agreed to meet him at a coffeehouse a few days later because I had decided to date him. However, Mickey followed me home. I saw him pass my house.

A few days later, he showed up at a store where I was shopping, although he doesn't live nearby. I invited him over for dinner, and he showed up again within the week, uninvited, and walked into my house while I was taking a nap! When I confronted him about entering my house uninvited, he said he was "concerned about my welfare." (I have systemic lupus.)

Abby, I dated Mickey a total of four weeks. Since then, he has continuously driven by my house and dropped off presents of books, cards, candy, flowers, etc. I have asked him not to come by uninvited or without calling first, but he just dropped off another book. He appears not to understand that his intrusive behavior is freaking me out. What can I do? Is this considered stalking? He hasn't threatened me, but I'm frightened and wish he'd stop pursuing me. What can I do? -- FREAKED OUT IN PENNSYLVANIA

DEAR FREAKED OUT: Tell the man plainly that you are not interested in a relationship and you want him to stop dropping by and giving you gifts. If he persists, begin keeping a written record every time it happens and notify the police, because his behavior could be considered stalking. You should also make certain to keep your doors and windows securely locked so you don't have any further unwelcome intrusions. You may also have to screen your calls for a while, and if he calls, do not respond.

DEAR ABBY: I need to know how to handle my mixed-up marriage. My husband is a preacher, and our marriage is falling apart. He cares more for another woman than he does for me. Every time we talk to each other, he always brings her into the conversation. It happens even when he's preaching. All I ever hear is that she helped him with his children when his other wives left him!

I understand that, but that was in the past. All I ever asked of him was to be there for me. Our sex life is terrible. He no longer has anything to do with me.

We have been married only 16 months, and this has gone on for half our marriage. It hurts me because I love him so much. What can I do about this? How can I make him understand? -- HURTING IN NORTH CAROLINA

DEAR HURTING: The time has come to stop reacting emotionally and think rationally. Just how many wives has your husband had? And why did they leave him? Could it be that they were treated the same way he is treating you?

Many wives make their husbands "understand" when communication breaks down through marriage counseling, and that's what I recommend for you. I don't know whether your husband still carries a torch for his former child-care provider or if he's actively involved with someone else. But you need more help than anyone can give you in a letter.

DEAR ABBY: I have a family member I love dearly, as does the rest of the family. This person has had an odor problem for many years -- but it is seemingly getting worse. We feel it is not only body odor but also lack of bathing and laundry.

No one in the family wants to be responsible for telling this person about it for fear of hurting this person or making the person upset and resentful. What should we do? -- UNSURE IN MISSOURI

DEAR UNSURE: You must speak to the person. By doing so, you will be helping, not hurting. What would be cruel would be to ignore the problem.

DEAR ABBY: I am a widow with four children. My mother passed away in March 2004, and 11 months later I found my husband dead in our bathroom after he had shot himself in the head. Needless to say, my world has turned upside down. I think I am managing pretty well, and I thank God every day for my children. I don't know what I'd do without them. However, I miss my husband more and more every day.

I do not know how I am going to handle all this. I don't know what I will tell my 3- and 4-year-olds one day when they ask me how their daddy died. I also can't picture myself loving another man, or being loved by one.

Am I destined to be a lonely widow? How can I tell my children the truth without destroying their lives? -- MOURNING IN ARIZONA

DEAR MOURNING: I hope you realize that all of the emotions you are experiencing right now are NORMAL. You have suffered two tremendous losses in a short period of time, so it's not surprising that you are feeling the loss deeply.

When your children are old enough to begin asking questions about their father, explain to them that although their daddy loved them very much, he was sick and he suffered from an illness -- depression -- and that one day he took his own life. As they grow older, they may need this information, because depression can run in families. They also need to understand that there is treatment for it. You do not have to give your children all the details at once, and it may be better that you don't.

As for being "destined to be a lonely widow," nothing could be further from the truth. But you will first have to deal with your own feelings about what happened. A source of support that might be helpful would be the American Association of Suicidology, which has hundreds of associated groups. It can provide you with referrals to local self-help groups for survivors. Newsletters, pamphlets, etc., are also available for a fee. The organization's address is 5221 Wisconsin Ave. N.W., Washington, D.C. 20015, and the Web site is www.suicidology.org.

Being a survivor of suicide can be isolating, but it doesn't have to be inevitable. By writing to me, you have already taken the first step in reaching out. I wish you happiness in the future.

DEAR ABBY: I am having a problem with a fellow classmate. He sits in front of me, and every day during class he turns around and asks me to marry him. Of course I say no, but he won't stop it, and it's starting to creep me out. One day he asked me why, and I told him because I have a boyfriend (which is true). Now he says he wants to hurt him!

I have tried asking him nicely not to talk to me anymore, but he still does, and he's in more than one class with me, so a seat change won't do much good. I'm not sure exactly what to say to him. Could you help me out? -- CREEPED OUT IN WINTER SPRINGS, FLA.

DEAR CREEPED OUT: The next time Romeo proposes, tell him that if he doesn't knock it off, you will tell your teacher and the principal that he's harassing you and making threats against your boyfriend. If that doesn't cool his ardor, follow through. He may deserve an A for effort, but he deserves an F in English if he can't comprehend what "no" means.
