Feeling lonely :\ (sorta ranting!)

I'm 28 weeks pregnant and my SO never spends time with me! He always says he's too busy working or he'll be in his shop.

He's only gone to 2 appointments (the first one and the gender one)

And I just feel so lonely and unsupportive by him. Like what can I do to make it better?

I've tried talking to him a million times!

Sometimes I just want to move out and leave him completely all because he never spends time with me and is not there for me and the baby at all :/

But then I live with him and his family and his family all are super thrilled for the baby except him.

Or sometimes I feel like giving the baby up for adoption so he won't go through the struggles of living with a single mom. But then my SO says that he won't let me take him.

I just don't know what to do anymore, I'm sick of it! :'/
