Lost stressed and feeling so helpless

I regret so much not listening to the people around me when I believed my ex husband had changed and gave him so much. The only thing I don't regret from the 7 years is my beautiful daughter.
I'm so over the stress. The upset. The constant abuse from him. I want it to end. He won't agree to sell the house, he's threatening family law court. I'm scared. I'm scared for my daughter to go into his world. He's been charged with manslaughter over killing someone on a drug crop, he's been done for drink driving, he does drugs, he friends are drug people, I don't want her growing up in that world. I don't want her to think those things are ok. I've never stopped visits or contact because she's what is important and knowing him is something. There is a current dvo.
He's smart. He knows what he needs to do and he knows how a look good in front of people. He knows how to get people to think he's some wonderful person. He won't sign for the sale of the house. I'm here thinking about bankruptcy just so the house can be sold. I'm so so over it all. I'm sick of feeling stressed and I'm over him trying to control my life and not letting go.
I'm so sick of fighting. I'm sick of the drama.
I don't know what to do anymore. I don't know what I'm supposed to do. I'm so lost. I'm worried and stressed and my family need there names off the house that my ex and I own together.
Sorry this is a rant. I needed somewhere to vent somewhere to get people to throw ideas at me.
