DEAR ABBY: Three days before my daughter "Ginger's" wedding, her fiance called to announce that he could not marry her because she's bisexual. It's something he knew about for a year but waited until three days before the wedding to mention.

Needless to say, my husband and I were shocked, embarrassed and devastated. We had gone to a wedding with Ginger and her fiance the Saturday before her wedding date, and they were excited about their own wedding, talking about the home they were building and about having a baby. By the following Wednesday, it was over! She has reimbursed us for half of our expenses for the wedding.

Ginger has since been involved mostly with women who have stolen from her, treated her badly and lied to her. We no longer trust our daughter because we thought she was happily engaged, but she lied when she told us how happy she was and how great she and her fiance got along. We cannot accept the current situation, and our relationship with her is now very strained.

We told her to live her life but not to bring these women around. Since then, she has chosen to stay away. We miss our daughter but are not willing to accept this behavior. We don't think Ginger is even trying to gain back our trust. Please give us your best advice. -- LOST IN LOUISIANA

DEAR LOST: Has it occurred to you that your daughter may be a lesbian who tried to appease you and her father by claiming to be bisexual? It is a blessing to all concerned that the wedding was canceled.

If you're a regular reader of my column, you surely must be aware that some women have dysfunctional "manpickers." In your daughter's case, she's having the same problem choosing her female partners. Rejecting her because you don't want "those women" around is not the solution to her problem. Instead, suggest she seek counseling at the nearest LGBTQ community center so she won't continue seeking love in all the wrong places.

DEAR ABBY: My boyfriend and I were excited to go on an $11,000 Caribbean cruise. His 22-year-old son was not that enthusiastic. We invited him to join us for dinner, shows or to play games, but the majority of the time he refused. The only time he'd join us was for events that were paid for in advance.

He called his mom, grandmother and girlfriend every night, but not once did he call his father's mother. To me, it seems like he's not interested in his father, grandma or me. The moment we arrived home from vacation, he bolted out the door to meet his girlfriend and slept at his mom's house. What can I do to bring this family together? -- SOCIAL DISASTER

DEAR SOCIAL DISASTER: Although at 22 your boyfriend's son is legally an adult, he didn't act like one on that trip. In fact, he demonstrated that he was uninterested and didn't want to interact with his father or with you. It is nice of you to want to bring him and his dad closer, but it's time for you to step back and let them work it out. Nothing you can do will fix this.

DEAR ABBY: A woman where I work refuses to acknowledge me. Every day for the past nine months, she walks by my desk and ignores me even after I've said "Hello" or "Good morning." I hate to seem petty, but I don't get how someone can be so rude.

Has workplace culture become so impersonal that people no longer have or employ basic social skills? It costs nothing to say hello or to smile -- it's the least she could do. -- FEELING INVISIBLE IN LOUISIANA

DEAR INVISIBLE: Of course the woman's behavior is rude, and even somewhat hostile. You might ask her if you have offended her in some way and see what kind of reply you receive. I agree that there has been a general decline in basic good manners over the last 10 years. However, one never knows what burdens those we encounter might be carrying. Depression, anger and stress can affect the way we treat others. My advice would be not to take this personally and, because you know she's not open to exchanging social amenities, to stop what you have been doing.

DEAR ABBY: Four years ago, I lost my husband of 20 years. After it happened, I told his younger brother, whom he was closest to, that I was going to write about him. However, some things have stopped me. I lost our dog six months ago and watched her follow a similar path as my late husband, which hurt me deeply. The other reason is, I believe his family may not want to know the truth.

His brother thinks my husband was a great man. He did have good qualities, but he wasn't the saint his brother thinks he was. He was emotionally abusive and he raped me numerous times. He often yelled at our dog for simple things, and he wasn't faithful, either. So -- should I write the story they don't want to hear? -- PEN IN HAND IN TEXAS

DEAR PEN: They say the pen is mightier than the sword. But if you want to continue to interact with these former in-laws, refrain from the temptation to use it to cut their brother down to size.

DEAR ABBY: My grandson's ex-wife is instructing their four children to "be mean" to his new 6-year-old stepdaughter. The children are all under 12. We do not speak to the ex-wife, but what can we do to stop this destructive behavior? -- APPALLED IN GEORGIA

DEAR APPALLED: I am so glad you wrote. Your grandson's former wife is behaving like a vengeful witch. That she would use the children to hurt a blameless child is appalling. You may be able to defuse some of this by sitting the "grands" down and explaining what you expect of them. Tell them that the little girl is not to blame for their parents' divorce, and that you expect them to treat her the way they would like to be treated. Then enforce the rules, as their father should.

DEAR ABBY: My boyfriend, "Rick," and I broke up 10 years ago and reunited two years ago. I'm in good health, own my own home, and am financially independent. Rick is nine years older. He owns his own home and is retired. We have been seeing each other every week for the last two years. He has spent many hours painting and doing repairs to my house. I cook for him and give him massages, and we have a fantastic sex life.

So, what is the problem? Rick is emotionally involved with another woman. He claims they aren't in any way sexually involved. Should I tell her about his involvement with me? I have her name, address and phone number. Rick refuses to tell her about me because he says it will "upset her." I think she ought to know. What do you think I should do? I love him dearly and don't want to lose him. -- BEING PLAYED IN NEW JERSEY?

DEAR BEING PLAYED?: Listen to your intuition. The first thing you should do (if you haven't) is ask Rick WHY that woman's knowing about you would "upset" her. (Does she think his relationship with her is exclusive?) The second would be to tell him you would like him to introduce the two of you. If he refuses, call her. You deserve to know exactly what's going on, which may be that they are much more involved than he has been admitting.

DEAR ABBY: My friend "Chris" and I decided to go on a weekend trip together. The tickets had to be purchased before they sold out. I told Chris I'd put them on my credit card, and Chris agreed to pay me back. Our original plan was to stay with a group of people, but at the last minute, Chris admitted to being upset that we weren't going alone.

Not wanting to upset Chris, I canceled plans with the other group. Chris offered to pay for the food, which I thought was great and would replace some of what was owed me. But when we got to the register, Chris stepped back so I would pay. Almost as soon as we got to the hotel, Chris and Chris' partner got in an argument on the phone and spent most of the trip arguing via text.

The night before we were supposed to leave, Chris and I got into an argument. I lost Chris in a crowd, and when I got back to the hotel, they were packing their bag and leaving. We sat down, talked and agreed tensions were high, but Chris still wanted to end the trip early.

The trip was three months ago. Since then, I have texted Chris multiple times asking to be repaid and have received no response. I thought maybe Chris is mad at me, but they still send me our traditional daily meme. Abby, they offered to pay me back a few times before the trip but never followed through. At this point, I don't know what to do. -- TRIPPING OUT IN INDIANA

DEAR TRIPPING OUT: At this point, you should write off the money you are due from Chris. It should be clear by now that your friend is a flake and has other issues as well.
