Yes, once a cheater, always a cheater! (For the most part, this is the safest way to place your bets.)

I never understood women that sleep with a married man, marry him when he leaves his wife, and then are suprised when he cheats on them!

True love will change him, you say? Most of the cheaters I have known have a real difficult time distinguishing "Love" and "Lust". (I'm old, and have known a few.)

Edit: Yes, I realize this was a woman claiming to be an ex-cheater, but I would like to know how many times a relationship started as truly devoted "true love" with a "Good Man" then went south one night when she went drinkin' and trollin' with her freinds. The only way I would beleive she has really quit cheating is when I hear she has married this guy, they have been married 30 years, and she can claim (and verify) that she has never strayed. Even then I would call it a 50/50 chance of actually being true.

It takes a certain kind of person to cheat... same as a it takes a certain kind of person to drag race, smoke, and steal. While anyone can change their ways, it is unlikely. Safest thing is to avoid cheaters if you're interested in a serious relationship.
