Fool To Think Part 2

Apparently I can't have a strictly sexual relationship with an ex and have it be strictly sexual.

We have been dating. And old feelings are rising, and I am not sure what to do about it.

What does this mean for me and L (the boyfriend)? Can I be with a man who has cheated on me in the past? Can I give that trust again? He says now that he knows what he lost when he lost me, he will have no problem staying committed and faithful. Do I believe him?

I have been told that my boyfriend is not planning on leaving his wife. He told me, so now what?
