Significant other

As the due date gets closer, it frustrates me how my s/o has barely acknowledged he has a child on the way. Completely ignores the fact I’m pregnant and shits on me for being happy about it. I’m due in 11 weeks. And today, I’ve decided to part ways with him. All I received was, “okay bye”. I’m not sure whether I should be hurt over it or just let it go, but it does make me cry. I’m not someone who’s in their mid 20s or 30s, I barely turned 20. I’m afraid to do this alone since he was all I’ve known, and to just get a bye kind of breaks my heart but just shows how little he cared. I just want to do what’s best for my baby and I.
