How could you abandon us?

I have no where else to turn to vent. I'm broken. My boyfriend of a year left me after seeing pictures from Nov of last year of my boobs and butt. I'm a long time advocate for women's rights and equality. He freaked out after seeing two pictures and the other NSFW stuff I reblog on my personal blog. I'm 9 weeks pregnant and he has adopted my two year old. He has told me I have to be out of the house this weekend and we are done. Since seeing my Tumblr he has said I have an obsession with porn and other ridiculous things. I just don't know what to do. He wants me to have an abortion but I don't want that even though he was completely against abortion when we discussed it. I asked him if he's willingly going to abandon his family and child over a pic of my boobs and he said yes. I'm at a loss.
