8 months pregnant talking divorce and custody

I've had a couple of posts about my husband and I's troubles. Well he finally decided he wants to talk divorce and custody of our first baby that's not even born yet. I've always had a feeling it wouldn't work out he had treated me differently my whole pregnancy and I knew he hated me previous to all this. I thought we would at least make it to have our son then see where things went. Unfortunately he wants to sort this stuff out tomorrow and I just don't think I can even talk about it right now. I don't wanna talk to or see him at all right now. My heart hurts. We have been together 11 years and he knows my dreams of my family and how I wanted my life to go. I always told him to please leave before we got pregnant if he didn't think we would last and he has waited til my last month of pregnancy to decide he no longer wants to be married or a part of my life but wants to be in his sons life. I feel like he did this to me on purpose. To hurt me, to ruin my life bkuz he knows I won't ever have kids or another family after this. It will always be just me and my son and I never wanted a life like this.
