Is it okey to be involve to a married man?

you need not advise her, she knows what she is doing and she is loving the thought of it.. you ask her " How would you feel if one day, your already a wife , and your husband is having a romantic affair with another woman? " maybe that would help her ponder. ..what comes around goes around! :-)

Well, I truely belive that what goes around comes around. I used to date married men. Not because I wanted to, but because men are just cheaters. I used to say that it wasn't my responsibility to keep a husband faithful, and if it wasn't me, he'd be cheating with someone else. And now I'm married and my husband is living with another woman. So I got it back 10 fold.

It is absolutely WRONG to get involved with a married man. You can tell your girlfriend that if that married man is cheating on his wife now there is no telling that he will not do the same to her...especially that she knows about him being married - Ask your girlfriend how would she feel if she was the wife and her husband was seeing someone else??? Hopefully that will bring her to her senses...

Well it really sounds like you've done all you can do in this situation. It sounds like she isn't going to listen no matter what. All you can do is keep telling her it's wrong, and not nice, and how would she like it if she were in the wife's situation? But other than that, you can't do anything, and she probably won't listen. It's nice that you are trying though! I feel bad for the wife that is getting cheated on.
