I think my husband is using me (long post)

I’ve been married to my husband for almost 2 years, we’ve been together for almost 3. When we first got together it was a drunken night and we had slept together then continued on throughout our relationship. off and on. He’s not an intimate person. and now that i’m pregnant my sex drive has decreased not only because i’m pregnant, but because the only time he touches me is when he’s trying to have sex. he doesn’t try to kiss me any other time. he doesn’t hug me or make me feel loved. I literally feel like i have to force him to kiss me. I feel like he tolerates me. I feel used just for sex. i’ve never met someone who makes me feel bad about myself. I’m smart when it comes to law, and some what math, but most of the time i’m not educated on some of the topics he talks about so he always makes me feel like i’m stupid. He’s always been quiet, he doesn’t really talk to people like that, including his own family. he chooses to isolate himself which is unhealthy. But I always invite him out with my friends just so he can see if he would like them, then when he chooses not to go, he throws it in my face that i’d rather hang with them than him. but it’s only cause they’re not boring. When i’m with husband now I don’t feel like myself anymore, I feel like an unhappy zombie, and he doesn’t see it. I can’t speak on how I feel cause it starts a fight. he thinks because he buys me materialist things it fills this hole in my heart that he’s not filling. (I don’t care about materialist things) I really don’t know what to do. 🤷🏽‍♀️ I seriously feel like i’m going through this pregnancy alone, and that he’s using me just so i can have his kids then leave me. he even talks about taking my UNBORN son from me. I’m literally forcing myself to stay strong but it’s hard. I DON’T KNOW WHAT TO DO.
