I started to read this thread, but stopped when it was obvious that the OP wasn't willing to listen. So, if I repeat anything that's already been said, I apologize.
I do want to point out something. You asked, in the beginning of this thread, if he was seeing someone else. You seemed to be worried about that. Worried that he might be "cheating" on you.
I find that amusing. He's cheating on his wife with you, he's had other girls on the side before you, and you wonder if he's seeing someone else? Duh! Why wouldn't he? Do you think you're so special that he wouldn't cheat on you? He's nothing but a cheater.
You get what you give. When you start screwing around with a married man, and really, that's all your relationship is, sex, and you know he's screwed around before, then do you really expect him to be faithful to you? Has he lied that well? I see through his lies, why can't you?
Bottom line, you are the other woman. You stepped into something you had no right to step into. Yes, he's scum, a pig, but you're no better. When you lie with pigs... well, figure it out.
