I feel further from him than ever and I’m not sure if we’ll make it

My boyfriend of 4 years and I decided to try, we wanted to have a baby. Now that I’m pregnant we are more distant than ever. He doesn’t understand pregnancy and doesn’t care to research. Tonight I asked him to brush his teeth because it smelled and I wanted to be close to him. His response was “god you complain about everything!” He vapes all day long and I tell him I can’t handle it smell it makes me sick. So yes I complain about every smell but can’t you give me a break I’m fucking pregnant! He’s so out of touch with my emotions, never asks how I’m feeling and doesn’t seem to care at all. I’m feeling lost and lonely and I’m wondering if we should break up. Anyone else feel this way?
