I have to agree with farmergirl here. He HAS a girlfriend and when he goes out with you he is cheating. He is being deceitful with her, and you know what? so are you.

Honestly, would you like some woman to do that to you? Well, it hurts and this girlfriend (remember you discribe her as a nice person) doesn't deserve this.

I have been in "her" shoes, only I was married and had a child and I was also NICE to a girl that worked with my husband in his restaurant. Well even though I was NICE to her and SHE NEW WE WERE MARRIED AND HAD A CHILD, she still went after my husband and they DID have sex. And my husband felt guilty and ended that "affair" but SHE STILL WANTED TO KEEP GOING AND WREAK MY LIFE!!!..

I finally found out about this a few years "after" it happened. My husband carried a lot of guilt about that event and he was actually mean to me because of HIS guilt.
I am going to be honest, I have NEVER gotten over that, and there is very deep part of me that doesn't trust my husband, even though he admitted it and made amends.

Everytime we argue, I have nightmares about him cheating on me.

I never believed in breaking up a relataionship or hiding the truth. And I would NOT respect this man because he is LIEING to his girlfriend. If he is not going to be honest with her, then he should break that relationship off. It just is not fair to this woman in my opinion. If he wants to date other women than he should tell this girlfriend so she can do the same and not put her emotions into him completely. This is something I could never do, if I knew a guy had a commitment to a girlfriend, or was married, I would not go out with him. I respect people too much for that.

Don't forget Karma.
