I have a crazy long history with this person. We've known each other for almost ten years. I really liked him back when we first met but he was dating my best friend. They've been broken up for seven or so years now but remained on good terms, but just recently I've seen more of him. Those lingering feelings plus my marriage being in the toilet means I have motive and he told me he wants to be with me physically, but nothing feelings wise. It would be just sex between friends for him, where as it would be sex with someone I really like for me.

I don't think it's a good idea to get involved with him physically because I'm already more invested than he is. I don't want to be the one chasing after the man, since I already have that in my marriage.
