I don’t want to be with my baby daddy

My boyfriend and i went on a couple dates, ended up having unprotected sex then i got pregnant. We barely even liked each other. Throughout almost my entire pregnancy i kept telling him i didn’t wanna be with him. My family shunned me and said i didn’t even try. So two months ago i moved in with him, our baby girl is 9 days old and my feelings haven’t progressed at all. I just feel stuck and we both agreed if i feel that way then we shouldn’t be together. I just feel awful because i know how it looks to a lot of people, like I’m abandoning my family. I just can’t take it. I’m not happy here.. he’s a good guy, just not my “person” and I’ve known that for awhile now. I’ve been suicidal and wanting to just run away because i hate feeling stuck

I just don’t know how to go about doing this. :/

I want to ask my mom if i can move back in with her for awhile until i get my money right but I’m afraid she will shun me and not allow me to just out of spite for me leaving
