I hate my husbands family, advice (LONG)

Okay, hate is a little strong but I really need to rant. If you happened to read "Family mad about baby gender", yeah that was me. I you haven't read it, I talked about how my MIL wanted a boy and we're having a girl and she's making me feel awful about it. I'm not sure if I gave the back ground story about my MIL but we have never really got along. First, I would like to say that my husband has not lived with her since he was 11 because of how much he couldn't stand to be around her and the men she brought home. So he lived with his grandparents. Now before we got married, my husband went to basic (he is in the army) and he would always write me letters because I was who he had spent every single day with, he was used to me and missed me. He didn't miss his mom because hed never see her anyway. She would call me and scream at me for getting "her" letters and phone calls and this was the beginning of me and her not getting along. She would say he was hers, not mine and that I was getting the info she should've gotten. Needless to say, he proposed to me after basic. After that things were quiet from the mother but I knew things were said behind my back. Then, I started getting shit from his grandpa. Basically because my husband was becoming a man and being in the military, he couldn't wait on his grandpa hand and foot, but for some reason I was to blame. He called me a slut to my face and kicked me out of the house when we were there. Later, the freaking uncle came into play telling my husband not to marry me and how awful marriage was and that he'd take him to a couple strip clubs and he'd get over me after a night of fun. This was all over the phone and I heard every bit. I HAVE DONE NOTHING TO THIS FAMILY BUT MAKE AN HONEST AND HARDWORKING MAN OUT OF MY HUSBAND. I don't even understand their hatred for me but it's obviously there. Now I'm being blamed for the gender of my own daughter and his family really doesn't care about my pregnancy anymore now that she's a girl. Now we are trying to get stationed in Washington which is halfway across the country for us but we love the idea. We're making our own journey and now I'm being told I'm just trying to take their granddaughter away? Like they fucking cared about her. My husband is now getting texts from his mom, grandpa and uncle about how are marriage will be ruined, how we can't pay our bills, can't take care of ourselves, won't be able to take care of a baby (most of this is from the mother) his uncle just really wants him to leave me. I just don't get why. We are a young couple but we don't fight, we pay our bills just fine, have great insurance, two reliable cars and always have food in the fridge. What can I possibly do?  My husband won't stand up for himself because he is used to being put down by them but I can't stand the way they not only treat him but us as a team. I only have one message from the uncle that I just happened to screenshot off my husbands phone, this one isn't as bad as the rest but it gives you an idea of what he'll say. I wish I had some from the MIL.. He never tells me when they happen because he knows it upsets me but I usually see them before he deletes them. They no longer talk to me. Please advice, anyone. It's stressing me out so bad and I know I shouldn't be stressed at 20 weeks because it hurts the baby so I'm trying to find some comfort and do something about this.
