Pregnancy Sadness

The father of my child has been acting like a complete ass towards me for the past couple of days now and it's really getting worse and out of hand I'm starting to regret having a baby by him. As of lately every single day he's hurting my feelings not being very nice to me at all and I really cannot take it it's making me want to become very violent and hit him because of the way he's treating me. I don't have anyone else no family no friends no nothing and I don't feel like no pregnant woman should have to go through this type of treatment especially not by the father of the child that you're carrying I don't know it's outrageous and it's getting out of hand for me. I don't know what to do.
