Single pregnant mother...

I'm 21weeks 5days today. The prospect of giving birth without the father who is still my husband legally at the moment (not for long though) scares me. He lied and cheated and didn't pay for a thing. I carried his ass for so long. Iv finally woke up and found the strength to get away from him. I'm still really nervous and scared. Any other single mums to be? How u coping? The hormones are making me so emotional at times. I get so weak and want him back because I think about my little girl growing up without a father. I did love him until a few days ago. Now I feel so cold towards him. I'm at peace with my decision. I'm just nervous about the birth, the newborn, raising a child alone? Anyone going through this or been through this?
