I had sex with a married man.

I just had sex with my ex of 3 years a week ago and he's married and has a kid now. I don't need the lecture, I know what I did was wrong but I'm so in love with him I couldn't help myself. His wife is terrible to him and to his family whom I'm very close with. He never pulled out and now I may be pregnant with his child. I feel like I can't talk to anyone about it because no one understands the situation. He was my first everything and I haven't had a boyfriend since him.
