DEAR ABBY: When I came out of my introvert shell, I began trying to find a relationship. I went on a few dating websites and met some great guys and some not-so-great guys. One of the latter had been giving me red flags since our first date. We clicked at first and shared many of the same interests and hobbies, but he wanted to move WAY too fast.

While our dates had always been in public places, he constantly wanted to get me alone, either at my house or his. He seemed put off when I asked if another friend could come. Then there came a time when my health was faltering, and our infrequent meetings became less important to me. I told him I was having health problems, but the next day he invited me out for another date like I hadn't just told him.

He either began to ignore what I was saying, or I was noticing it more frequently. Because of this and other things, I quit responding to him. This has now spiraled out of control. He has contacted me on every social media app, on my phone and by email. I am upset for a number of reasons, but I feel guilty ignoring him.

My family and friends say I am doing the right thing -- that responding to any of his communication will give him the idea that I'm open to communicating again. I do not want to start talking to him again, but I still feel awful about ignoring him completely. What should I do? -- WONDERING WALLFLOWER

DEAR WONDERING: You may be feeling guilty because you are ghosting him, which I believe is bad form. Send him a text or an email telling him you haven't responded to his attempts to communicate because you are not interested in a relationship, and he must stop trying to contact you. Period. If he persists after that, you may have picked up a stalker, and you should file a police report.

DEAR ABBY: Our son is engaged to marry a young lady our family can't stand. No matter what we are discussing, she turns the conversation to long, boring stories about her friend, her aunt, her cousin, etc. Nobody cares about these stories, and they are constant. Our two daughters and their husbands roll their eyes and limit their time with her. My husband leaves the room. Even my 95-year-old mother, who is partially deaf, can't be in her company.

Our daughters think we should tell our son not to marry her, as it is ruining our close family. He doesn't seem to notice it, seems to love her and will be hurt. Have you any suggestions? -- STUMPED MOM IN THE EAST

DEAR STUMPED MOM: If you do what your daughters are suggesting, your son is almost guaranteed to be offended and become defensive. It could very likely alienate him and his fiancee. An alternative might be for you to talk privately with your son and point out that his fiancee needs to curtail her speeches because, in case he hasn't noticed, they are so long that she has literally been losing her audience.

DEAR ABBY: I live in an apartment building. I am quiet and keep to myself. There's a concierge here who is incredibly nosy. When I pick up my package, she asks, "So, what's in the package?" as if I'm doing something nefarious. She's also a terrible gossip and a liar.

At the front desk, as well as to management, she has accused me of doing things that never happened -- sexual impropriety, drug and tobacco use, etc. I started receiving strange, unsigned text messages with the same accusations. I can usually recognize who contacts me. My contact information was available in the office.

This woman recently accessed my apartment using a master key. Fortunately, I was home at the time. She was fired, but she was back last weekend. Our manager said she is here "temporarily" until he can find a replacement. There are multiple copies of these keys out there, and I no longer feel safe in my own home. What would you do if you were me? -- INVADED IN GEORGIA

DEAR INVADED: Document all the incidents that have happened. If they continue, write down the time and date they occur. This will prove beneficial should you need to escalate the matter. That the manager rehired a fired employee because of a staff shortage is disappointing. (It shouldn't have happened, and there are better ways of augmenting staff needs.)

Because your manager has been unresponsive, reach out to the property owner or management company and report what has been going on. If that isn't effective, report the matter to the police. Your safety and well-being must come first.

If you can afford to engage an attorney, consult one for advice on legal options you can consider to protect yourself from harassment, hostility or bullying. If the situation doesn't improve, consider finding a new place to live.

DEAR ABBY: I am currently married, but I'm looking to get an annulment or divorce. I have met a woman I am falling for. She knows my marital status and feels the same way about me.

I promised her my marriage would be over within eight months, but she feels that with my divorce, my wife should leave even if I move out and rent out my portion of the house. (My soon-to-be ex and I currently live on opposite sides of the house.) Do you agree? -- MAKING CHANGES IN NEW YORK

DEAR MAKING CHANGES: Whether or not I agree is irrelevant. The person who should be answering this question is the attorney who will represent you in the divorce. If you really plan to leave the marriage, make an appointment NOW to discuss it.

P.S. And, please, give yourself time after the divorce is final rather than tie the knot again on the rebound.

DEAR ABBY: I'm a single mother of two children, an 8-year-old daughter and a 9-year-old son. My daughter's father is involved; my son's father is not. I was diagnosed with pulmonary arterial hypertension (PAH) when my daughter was born and given two weeks to live. My condition has markedly improved, and I am on the best treatment there is for it.

To safeguard my son in case something happens to me, my parents and I did a third-parent adoption. With this new law, I was able to add my parents to my son's birth certificate without giving up my parental rights, and I remain the sole custodial parent. He stays with my parents three evenings a week.

The problem is, my mother blatantly favors my son over my daughter. Last year, she planned a Disney cruise for only herself, my son and me. I understand life is not 100% fair, but her favoritism goes beyond just tickets and trips. It's everything from gifts and attention to tone of voice and how many pictures are on the wall. Everyone around us sees it, especially my daughter. Please advise. -- UNEQUAL IN OREGON

DEAR UNEQUAL: I'll bet your daughter notices it! The person who can put a stop to it is you. Consult the attorney who helped you with the custody arrangement and explain that what has been happening is not healthy for either of your children. After you find out what your options are, including possibly changing the custody agreement, confront your mother about her blatant favoritism. And be glad that your daughter's father is as responsible as he seems to be.

DEAR ABBY: I used to hang out with my friend "Brian" and his girlfriend, "Jenny." We all lived together and would spend almost every weekend together. They broke up and went their separate ways 14 years ago. Jenny is single, and Brian has a steady girlfriend now. I still talk to them both, but not often.

Jenny messaged me recently on social media. We shared some photos and talked about the past and present. She said she has her own place and is doing well. I suggested that maybe I'd stop by one night after work. She said she'd like that and sent me her phone number to set up the date and time.

My question is: Should I visit her, and what if something sexual happens? (Trust me, I wouldn't rule it out.) Should I ask Brian for his permission? Are Jenny and I heartless for wanting to meet up? -- PAST, PRESENT & FUTURE FRIEND

DEAR FRIEND: Because you are uneasy about crossing some kind of boundary if you visit Jenny and there is chemistry, contact Brian and say, "Hey, guess what. I reconnected with Jenny and she invited me over. Do you have any objection to that?" I cannot see how, 14 years after their romance ended, he would have an objection. Then visit Jenny, and que sera, sera.
