Low sex drive...

My hubby and I have been together for almost five years (married for two). I'm 36 weeks pregnant and we got in to an argument about sex. To the point where I don't know if he's staying or going. I have a low sex drive and think it's because of what happened to me as a child (I was molested by the neighbor). I want to be more sexual and intimate with him, but it has been hard for me. I feel put off at times when I try, and I get blamed for it. I don't want to give up on our marriage, but feel that he has. 😢😢😢
