My marriage feels like we're roommates

I (22f) have been married to my husband (22m) for about a year now and honestly, it feels like we're roommates who occasionally fuck. I love my husband, but recently it feels like I'm just an inconvenience to him. When our relationship started it was passionate, loving, and exciting. It felt like everything was perfect. We used to be intimate almost every chance we got, with him initiating, but now we maybe have sex 3 times a month, if I initiate. I feel so unwanted and unloved and every time I bring it up it's brushed off like it's not a big deal. I feel like an incubator, I've felt this way for months and now we're 8 months pregnant. I was originally the breadwinner of our relationship with him staying home and taking care of the house and our pets. We recently had to move due to financial hardships and I can't find a job that will hire me this far along. I'm starting to feel like staying wasn't the right choice. I feel like I should have left when I found out he cheated the first time. It feels selfish to say but at least maybe then I wouldn't be stuck in this house feeling like a piece of furniture. I've given him everything I have, given up so many things to be with him, but for what? I feel like I'll never be enough for him, I'll never be her. I know it's stupid but I don't want to leave. I don't want our child to grow up like I did.
