First I want to say kudos to dm383 for coming forward with his story which might possibly shed some light on the "Why did he do it?" aspect. It's difficult to admit the low times in your life.

I just want to add to what others have said... Telling the wife will most likely do no good because, A.) She probably already knows he is a piece of crap. Or B.) She has no idea who you are and won't want to believe you so she will be in denial about the whole thing. If option A is true, she probably will just accept it. I feel for you Mellissaaa, as I've had my own experience with the evil spawn of satan girlfriend that couldn't tell the truth, period. What goes around comes around.... and he will reap what he has sown. Tell him off, from long distance, tell him it's over, and walk away without loooking back. (I know, easier said than done.) Good luck, I will pray for you. Hey, things could be worse... imagine if you didn't have Pixies?!
