I won't go too far into the backstory, but I have a very good female friend that moved early last year and I took it pretty hard. So much so, that it almost cost me my marriage.

Anyway, I sometimes see people that I know she hooked up with and I'd get get a little jealous. There's a guy that I work with that was talking the other day about the couple of times he hooked up with her and I got insanely jealous, almost to the point of having to walk away.

Why do I keep getting these jealous feelings and how can I get rid of them? It's about to drive me back down again.
