Dear Prudie,

A friend of mine (age 25) has been having an affair with a married man (39 with two young kids). It sickens me, and I have been questioning whether I should maintain my relationship with her. At any rate, it has been going on for over a year, and she does not show any signs of breaking up the relationship despite advice from numerous friends. I am tempted to anonymously call his wife and give her a tip, such as, "Watch your husband" or "Your husband is having an affair." I can't stand to think of this poor woman at home with two young children, unknowing, while her husband is out gallivanting! Is it wrong to meddle with fate?

—Confused and Distressed!

Dear Con,

Fate being fate, it cannot be meddled with, but you definitely should not meddle in your girlfriend's affair. It is rotten, granted, but why on earth would you want to lay this information on the poor wife? These things have a way of working themselves out without phone calls from informers. Often, by the way, the wife knows. Whatever might happen as a result of your phone call—if you did make it—is nothing you need on your scorecard. The short answer is that this situation really has nothing to do with you. Cool your jets, and perhaps find a hobby.

—Prudie, properly

Dear Prudence,

I am very much still in love with my high-school sweetheart, though we are together no longer. When we went to college, we broke up. I am now with a man I have been with for over four years. Though I love this man, I know we are not meant to be together. My high-school sweetheart is now engaged to be married (within a month or two). I have seen him on two occasions in the last year, in which he has declared his love for me and told me he is "settling" by marrying his fiance. I turned down his advances, not for lack of love but out of respect for his new relationship, though I told him I did not love him. (I didn't want him to think about me.) Now that his wedding is approaching, I find myself wanting more and more to tell him how I feel. This is not because I want him longing for me but because I truly love him. 

—Confused

Dear Con,

Prudie can think of no reason why you should not make a clean breast of it. At least no one is married at this point, and who knows? You have conducted yourself well and honorably. And it's not as though you set about sabotaging his plans; he came to you. If the two of you wind up together, it would be one terrific love story. Let Prudie know what happens.

—Prudie, romantically

Dear Prudence,

For the past year I have been attracted to the father of one of my son's friends. He is divorced, but I have been married for 10 years. It's not a perfect marriage, but it's not entirely awful, either. We don't communicate very well, and he is very jealous. He has always made me feel like I am wrong, no matter what the subject or fight is. I was not attracted to this other man right away, but gradually I began to have feelings for him. I don't know him very well, so I can't figure out how the feelings became so strong. He knows how I feel because I have written him letters, and he has called me to say he has a girlfriend. Because of that and the fact that I am married, he will not even meet with me to talk about this. There is virtually no chance that we will ever get together, because I can't see me leaving my husband just for the slight possibility that I may be with this other man. So why am I not able to get over my feelings for him? I think about him all the time, and I don't know how to stop, even though I am aware that this is wrong. I also wonder if I should confess this to my husband. I know he will be very upset and maybe leave me over it. And he would probably go after the other man, even though none of this is his fault. Please help!
