sexless in bed

How many woman have been dealing with a partner who stop having sex with them ever since he found out your pregnant? When I first got involved with my man our sex life was passionate and intense and how I got pregnant.. I would never imagined it turned into a sexless relationship where he's not even interested to kissing or cuddling me anymore. He doesn't ever touch me or attempt to be intimate with me anymore and when I was highly horny in my 2nd trimester he would make an excuse every time not to engage. I've never felt so completely rejected by a partner before especially one that sex was such a major role in satisfying me in the relationship. Now I've learn to masturbate something I've never done before in order to not be sexually frustrated with him all the time. I've asked him what's wrong and he just brushes it off. I was even at the point I was gonna leave the relationship cause I started thinking he must be having sex with someone else tho he continues to deny it. I don't understand.. I'm so hurt. I'm adding a pic.. please tell am I just gross!?!
