I Dont wanna be pregnant anymore!

I want to cheat on my boyfriend. This is our first child and I'm constantly reminded that a pregnant in a good or bad light. It's annoying can't have a drink cause I'm pregnant I shouldn't be working because I'm pregnant be careful because I'm pregnant he's stressed because I'm pregnant can't have sex cause he feels weird or "that's the last thing on his mind." Because I'm pregnant.... I just need a release real physical intimacy without the guilt... When I bring it up I'm wrong for thinking about it when I talk about the baby I wrong for thinking about her I just want to pound my head in it's giving me such grief not sure if I ever want to do this again with him.. makes me feel like I won't love him the same after replaying all the things he said in my time of need.
