My first suggestion to a woman in your situaton is to get a job so you are not helpless. So keep trying. I understand the difficulty today. Money gives you some independence. I would suggest martial counseling if you wanted to hold the marriage together, but it sound like you aren't so interested.
Ladies often overlook their closest ally in their parents; don't assume they don't care. Have you talked this over with them? You said you would be trouble if you went home. Maybe so, but talk to them. Do you have any friends that might lend a helping hand temporarily? Could you share an apartment?
Let me point out that jkgrandma gave some very good suggestons in her answer to you.Some of those take money too. I read her answer. It is very good.
Is there a mental health center or a church counseling center that could help you share your burden and maybe offer some help? Do you know there are food pantries usually run by churches that give out food or help with other needs?
I do think it sounds like your man is becoming harder and less sorry as you put it. He will likely get worse. Abusers usually do. They start out verbally and let words hurt you and then they hit you and hit you harder and perhaps break bones and are always sorry, oh so sorry after they nearly kill you. Women usually feel sorry for the abuser and so it is alright. Plese do not go dowln this road. The earlier you get out the better if the abuse has started already. Temper is the cause and he says I can't help it.
But I am so sorry Honey. Please forgive me and I will never do it again. BUT it happens again! Please keep looking for that job and maybe for someone you can move in with. It is for your own health and well being if you are being abused.
Never lose hope and don't lose confidence in yourself. When you are mistreated guess what goes real fast--your sence of self-worth, your confidence, and of course you begin to think there is no light at the end of the tunnel of darkness and depression you are in. There is hope. There is a way. It seems like there is no way, but if you hang in there something will work out. Believe in yourself and you will make it. God will make a way for you.
