I've asked my close friends and so far they are split on what I should do. Sorry, long story, but I'm torn on this one. I'm in a weird situation. I have this guy friend who lives in another state and we've known each other for 7 years. We have shared everything about our lives and are very close, but not in a sexual way at all, and never have been. Just a truly "guy friend." Well, he did a little bit of overshare with me the other day. He got married not even quite 2 years ago to someone I have never met, and I never pegged him to be the type to cheat. About a year ago his wife got a job in another city about 2 hours away, and they've had a commuter relationship since then. They are together every weekend in one town or the other, and he can take a lot of time off because he works for his Dad, so they are together 3-4 days out of the week at least, and go on a lot of vacations together (he has money). They are both very ingrained in each other's families also, and both families are close too since their marriage, and they all attend weddings, parties, funerals, etc. together. I thought they had a wonderful relationship. But, in the past he has shared with me that even though they are apart a lot, and when they are together for vacations and long periods of time, his wife's sex drive is much lower than his, and she is young, and it bothers him. Well, the other day he writes me and forwards this email and pictures of an "Escort" he hired!!! I don't consider her an escort, I consider her a PROSTITUTE!! I was completely SHOCKED!! It made me almost sick to my stomach. He told me has done it before and is also flirting with a couple of girls in his classes. I gave him the lecture about his innocent wife, and that condoms don't protect you 100% from aids, herpes and other stuff, and if they did oral you might as well not even used a condom!! I told him if he wanted to sleep around, get a divorce and not subject his innocent wife to any number of venereal diseases, or to be honest with her and tell her how miserable he is with their sex life and work it out with a counselor. Did he listen? NO!! He went through with it!! I told him I had absolutely zero respect for him, that he literally turned my stomach and I want nothing more to do with him and no longer wanted to communicate with him, EVER. So, my question is: Do I do nothing and let his wife be subjected to any kind of STD, including aids, OR do I anonymously let the wife know because I have never met her? I don't want to inflict that kind of pain on someone I don't know!! BUT, my moral side wants to protect her!! GOD I HATE THIS GUY!! I feel like if I did let her know anonymously I could be saving her life, but she and both of their families may turn on me or try and find out who I am, when I want NOTHING to do with it. This would literally tear two families apart!! Also, I'm sure he would figure out it was me who anonymously let her know. Half of my friends have said "You HAVE to let the wife know, she is in danger of possibly even losing her life" and the other half have said "Let it go, he will hang himself in the end and she will eventually find out." (Generalizations of what they all said combined.) I have NO IDEA of what to do!! I HATE THIS!! I feel guilty either way I choose. I sure as heck don't want the families coming after me!! You know how that goes, sometimes it is the person who spills the beans who is blamed and turned on. But I am so afraid for her. Please give your opinions or advice on what I should do, it helps to have an outsider's opinion. Thanks in advance.
