Is she in danger of contracting a disease from this douche? Is she REALLY your friend? That should answer your question.

I would pull him aside and let him know that people are suspecting something is up and are talking. I would let him know that if he's not careful someone is going to spill the beans. Then I would back out. Something similar happened to me. My first wife cheated on me. I saw all the signs and chose to not believe it. When I confronted my friends, there advise was to pay attention to the signs. When I confronted her, she admitted the truth.

From looking at the other side of it......yes you would want someone to tell you.

But the position that YOU ARE IN NOW, its best to stay out of it. Act like you don't know anything about it.

I would stay out of it. I base my suggestion on experience. My best friend from school days and beyond was cheating on his wife who also happened to be friends with the Mrs. and I. I tried to talk sense to him, tried to convince him that he had a family (2 kids) he was responsible for, blah, blah. Said some things about who he was stepping out with that I regret now, but I felt strongly I was trying to save their marriage. I was naive. Basically, it ruined our friendship. Things aren't just the same and it has been years since we have gotten together.

dishonesty is always the best policy.

I still want my question answered.....that way I can make an informed decision.

Even if it were true, you're not going to get that response.

yeah, that's prob true, but whatever is motivating him makes a big difference...imo

What do you suspicion is the primary motivation?

D just got engaged not too long ago. If he's trying to hook up with the wife, then he'd be a major hypocrite.

Well, apparently he is engaged....so apparently that rules that out...apparently.

Soooo.....heretofore, my answer would then be.... talk to your f-in friend, dude and ask him why he's cheating.

If you have to confront him about it, do it suttely. Have a guys day out. Golfing or something. Something where there are good looking gals and beer around. A setting that will allow some good old "man talk" like "check that gal out. Damn... she's fine. I'd like to jump her... how about you?" Let it lead into some other gals from you two guys past. And when you get to the particular gal in question, say "Oh man... how about ______? I would love to jump her."

You will probably know from his response weather to pursue the matter, or move on to another gal. And have another gal in mind in case you need to advance the conversation quickly.

And who knows, maybe even a week or two later, he may confide in you about the situation. But be patient... and let him bring the situation to the forefront after you have led him there. Play stupid if he goes there... whenever that may be.

And if he never goes there... follow the other peoples advise and do not confront him/or her with the news.

Why can't he ask just straight out? "dude, why the hell are you ****ing another chick?"

Why do you want to rob all these women? That just doesn't seem right...

Any friendship that doesn't have honesty as the foundation really isn't much of a friendship in my book. Some folks like having a large quantity of friends; myself, I prefer quality.
