Can't stop crying

I'm 12 weeks and thinking of divorcing my husband. I have a one year old son already. It's gotten so bad lately and today he pretty much threw a fit when I wouldn't have sex with him and than slammed the door and left than started texting me mean things like throwing tge fact I had sex with other people before we were together (when I was 14-15) he throws this in my face all the time and knows how bad it hurts me. And the fact I can't do anything about it... I can't change my past... But I can't keep going in a hateful relationship.
