I'm having an affair, what should I do?

I've been married for 8 years. For the last 6 months I have been having an affair with a client at the salon I work. I get away with it because my husband is out of town on business. I've known the guy I'm cheating with for about 2 years there has always been a lil flirting but always innocent. Until I made the first move by calling him and inviting him out. He was sweet and attentive which was exactly what I was lacking at home. But as time went by he just started acting like an @sshole. His idea of communicating is texting and it seems he only comes around when he is horny.Sometimes I wonder if he acts this way because he knows there cant be anything between us. So a few weeks ago I told him I left my husband to see if it would make a difference. Recently I got fed up with it and stop being as clingy as I would normally be. He also went on a trip which helped. Now hes back and wants to meet up . Should I do it and risk getting disappointed again?
