I'm sleeping with my best friend's fianc

I didn't like him at first because he was treating her bad, but now I've got him under my skin.

Dear Cary,

My best friend got engaged to the father of her kids about four months ago. I didn't like him because in the beginning of their relationship he used to cheat on her and just treat her terrible. I've known my best friend a little over 14 years now and I hold a grudge toward him because of this. I really didn't like him until he confessed to me that he liked me and had feelings for me the first time he met me.

At first I wanted to tell my best friend, but I didn't want to get involved in that so I just decided to keep it to myself. Ever since that day he's been texting me telling me that he wants to make me happy and just wants me to fill a void that he's missing. He says that he loves my best friend but he feels incomplete. But now I caught feelings for him because I got to know him more than what I knew before. I understood why my friend was still with him even after all the cheating and lies because underneath it all he is a good person.

So I finally gave in and slept with him and now his feelings for me have been getting deeper. Now I feel the same way. I know what I'm doing is wrong but I can't seem to shake off these feelings for him. I'm stuck and don't know what to do.

Dear Stuck,

You need to end this relationship. If you don't, you will get hurt. If it is too difficult to end it while you are still living where you are living then consider moving away for three months to a year. If you have relatives, say, in California, or somewhere like that, ask them if you can come and stay with them for a while.

If you cannot get away, then you are just going to have to break up with him in a direct, straightforward way and stick to your decision. Tell him that this relationship is wrong and it is over and that is that.

After you have broken up with him, here are the rules: You cannot see this man. You cannot have coffee with him or talk with him on the phone. You cannot accept texts from him. You have to cut off all contact with him. You have to end this thing.

You may continue to feel a strong desire for him. That is OK to feel. You can feel it. It won't kill you. You can live with desire. You can also redirect the desire. If the desire is mostly sexual, find somebody who turns you on to have sex with. If it is also that he gives you a warm feeling, a feeling of being liked and cared for and understood, then seek this feeling too, with friends or family. Find someone -- not your best friend! -- that you can confide in about this. Give yourself what you need. But end this relationship.

For some readers, the question of whether you confess to your friend that you slept with her fiancé will be the big issue. I'm sidestepping that, OK? She may find out. She may not. You may feel compelled to tell her. You may not. He may tell her. I am focusing on what you must do now and in the long term to build a good life, given what has happened.

And I'm thinking about your best friend. I feel for her too. What is she going to do? Do you want her to marry this guy? Really? Will she be better off with him or without him? What is he going to do for her? How is he going to help her live a good and happy life?

I am really concerned about your friend. She has children to support and a fiancé who cannot be trusted. The two people closest to her are deceiving her. She is a single mom who must support her children.

Plus, I must say, you owe this friend of yours. You have deceived her. You owe her. So after you have broken up with this man and severed all contact with him, I would like you to turn your attention to your friend. Ask yourself what you can do for her. Wouldn't it be great if you were to settle down and get married and have kids, and your kids and her kids could grow up together? That would be a pretty good way for this to end up.

There are many reasons why she needs your presence. Given the situation she is in, she may be in for a hard few years and could use a friend nearby. This man, her fiancé, may cause her all kinds of heartache if she marries him. And if she does not marry him, she will be a single mother trying to make ends meet. So either way, she is going to have her hands full. And you are in a position to act in a new way, a way that will make you feel good about yourself.

What if you could find a good man and fall in love with him and marry him and have kids with him and live near her? I know you've been deceiving her but you can change. Or maybe you don't have kids. Maybe you stay single. But you put together some kind of stable life. If you can put together a stable life and live near her and remain her friend throughout the next 20 years or so, while her kids are growing up, you can do a very good thing in this world.

People don't tell you these things. We see families grow up around us but people don't really tell us why some families and friends remain happy and others drift apart and end up lonely and bitter. Part of it is that some people are just situated near the ones they love. Sometimes it's geography. So think about it at least. You obviously care for this person even though you've been deceiving her.

Twenty years may seem far in the future. But before you know it, 20 years will have gone by. It is in your power to decide where you are going to be while those years go by.

So that is what I would do. I would break off this relationship firmly and permanently. I would try to settle down and live near this friend. I would try to live a good life and maybe get married and have some kids and be there for her, so that whatever happens, whether she marries the fiancé or decides that he cannot be trusted, whether she finds another man or stays single, you can be a stable, ongoing presence in her life and in the lives of her kids. And you can continue to enjoy her presence as a lifelong friend.

It can be done. It would be a good thing.
