Husband hates my pregnancy body..

So since I'm 5 months pregnant there has been lots of changes going on with my body stretch marks everywhere, nipples getting darker and bigger you know the usual but instead of feeling a sense of confidence I feel horrible and disgusting. Yes I know it's not how I should feel because I'm creating a beautiful little boy in my womb but my husband has a way of making me feel shitty even when I feel so beautiful. I change in front of him and when I take my bra off or put it on he makes this fake gag and laughs at my boobs. He doesn't mind the stretch marks but he says my butt is shrinking and it makes me unattractive so when we go out he looks at other women and tells me "look at her ass" and it just makes me feel horrible because here I am creating our child and I don't get a compliment I haven't gained any weight from being pregnant either. I don't know if I'm over reacting because of the hormones but overall I feel gross. The man who is suppose to support and love me most especially right now has failed me I don't think he will change because when I tell him to stop he thinks I'm being "a drama queen" I really just wanna leave till my son is born.
