Why ?😭😭😭

Why won't my bf have sex with me anymore ? He always had an excuse & it was never like this until I became pregnant. I'm miserable due on Sunday & no contractions & im trying to do everything I can to go into labor. This isn't helping my labor or my self esteem, it's breaking me apart I feel like he is disgusted by me & I cry myself to sleep every night that he rejects me & just goes to sleep like nothing. I don't understand what I did, he used to never leave me alone.
