First I do not believe once a cheater is always a cheater. I cheated on every boyfriend I ever had and then I met my husband. We've been together nearly twenty years and I have never even so much as held another man's hand during this time, including the time we spent together before marriage...
I am surprised that I have never heard any of this from you. Very interesting stuff, if you think of more, I'd love to hear about it on our next lunch date. ;D
When people hint around a subject just so you can ask questions, then they say "I don't want to talk about it." If you don't want to talk about it, then keep yer trap shut about it in the first place.
