My husband isn't attracted to me anymore

As

My husband and I have been married 6 months but we've been together for a 3 years. We were crazy and decided to have a baby after only 3 months of dating, so pretty much our entire relationship has been centered around me being pregnant or a mom. We used to have an amazing sex life, he couldn't get enough of me when I was pregnant. After I had our son he was absolutely in awe of me and things just kept getting better. Now our son is 2 and I've gained about 50lbs in the time since my husband and I met. I'm a stay at home mom and I still breast feed which my Dr thinks is slowing down my metabolism so my body is always prepared to continue making milk even if I can't get food (thanks to struggling with eating disorders). We've been trying for 9 months to have a second baby and I recently had 2 miscarriages in two months. Things have just plummeted straight down hill for us. My husband won't make out with me, he won't go down on me, when we have sex it's purely for the purpose of making a baby even though I told him I don't want to try anymore. I feel absolutely disgusted by myself because he can hardly keep it up for me anymore. When we are having sex we have to do exactly what he wants or he starts getting soft. If I try to kiss him during sex he loses his erections almost immediately. I try giving him blowjobs but he has no interest at all. He watches porn and masturbates every day, which never used to bother me because he still wanted me too. But now I've been completely replaced by porn. I have suggested maybe we try and open relationship since neither of us are getting what we need sexually (we are great outside the bedroom). But he has absolutely no interest in having sex with anyone, period. Evey day that goes by and I try to have sex with him, I wear lingerie, I try giving him blowjobs, I've even had my mom take our son out so there's no possibility of being interrupted, but nothing works. He's just not interested in me anymore and it Fucking hurts.

All I want is for my husband to be attracted to me again. I'm trying my hardest to lose weight but it just won't budge
