He's on facebook.
I don't know what his "facebook" name is for certain-but I think it might be the same, because I recall seeing recognizing him as the xeromag-guy.
I was a cheater after I married, before I found poly.
Prior to marrying I was in open relationships a lot, often more than one at a time for significant periods of time.
I agree that one can change.
I don't believe that "once a cheater always a cheater". Just as I don't believe that once a person has failed at something they will always fail at it and never learn how to succeed.
