Lonely pregnancy

I went through a rough breakup, got counseling for victims of Domestic Abuse then as I thought I was starting my life over,  I discovered I was pregnant from the last encounter I had with my ex. He hates me and wants me not to have the baby because it will ruin his life. We are both in our 30s and could raise a family. He has never forgiven me for having our son, now almost 3 yo. I'm jealous of women who have a man that's excited and supportive and holds her tummy. Seeing pics like that actually breaks my heart now.
