<human>: Can you condense the text into three sentences or less?

I got married at 21, but divorced him at 22 because he was physically and mentally abusive.  During our relationship,  he refused to work after he lost his job, so I was forced to use my credit card to buy basic food and pay expenses (or so I thought) after he blew through my savings. When we divorced, I found out a lot of the money I'd given him had been used on Steam and other online gaming platforms. I was stupid for taking cash advances, I know. I was stupid to trust him, I know.   
Now it's two years on and I still have a lot of debt, about $4k worth. I have no real proof of anything,  and we live in Finland so the laws are different.  I can't afford my monthly payments anymore.  I just applied for a card that has no interests on balance transfers for 15 months but I'm scared that I still won't make any progrrss.  
I've thought about teaching out and asking him for money, but he scares me. I want him to own up and at least pay half of this, but I'm scared of him. Really, really scared of him. And the last time I mentioned it 18 months ago, he told me to ask my new boyfriend for help, which is ridiculous.   
Does anyone have any idea at all what I can do here?
<bot>: abusive ex used me for my savings and credit cards.  I can't afford the payments.  Not sure what to do.
