He is not supporting you. Don't let that man abuse you any longer, you need your health and sanity for your children. Children with no father is better than having an abusive father, I don't see a reason why you need to stay with him. File for child support and assistant, and a restraining order against him , he is controlling and manipulative- you are in no situation to get pregnant and yet he still tricked you,that's not right. Don't think this is your fault in any way
