An old school friend kept talking to me as if he really liked me and had an affair. Then I got sick and tired of being used for sex all the time. It would always lead to sex when we hung out. He'd send me a really long email saying how he's sorry and that he misses me and wishes we were friends again and all this crap. I finally blocked him for good and it was such a relief. It's not with a married man but still not right. Everyone else has said what they have to say. I hope everything goes ok for you.
