I want to be over it

It's been 4 months that my husband cheated on me and left. I'm 31 weeks pregnant with his child and doing my best to get over it. He doesn't want to talk to me about the divorce anymore which is odd because he wanted the divorce. Now it feels like I'm the only one who wants it to get my life back on track and forget the heartbreak. He just ignores me and the baby. I'm crying tonight and I don't know how to handle the situation anymore. Being pregnant with our first child doesn't help and the fear of labour and everything after that grows daily cos I know I'll be alone.

I need some advice on how to get over it or something... I feel so depressed right now.
