Breaking up with baby daddy.. single parents I need advice

I’m 5 months pregnant, my partner has just completed ruined my trust I had for him and I can not be in this relationship with him.

The only reason I’d be staying with him is because I don’t want to be by myself to raise this child. I have no friends or family in the same town as me. I don’t know what to do .

I know I can’t be with him. Please single parents, how do you do it ?! I’m genuinely scared and I don’t want to stay with him just because of the baby
