We would not play with cheaters either, whether they are male or female. I the F half, was also a horrible cheater in my early 20's and I can say that the experience alone has changed me. Sometimes that quote from ES about "Once a cheater always a cheater" can ring true, however not for me. And I see in another post here that others have learned from their mistakes as well!
It would make me feel totally awful to know that I was contributing to any drama in a cpls life, been there and done that and I don't expect any of that in my relationship and would hope that my friends feel the same.
