You will be okay, and you are right to let go of the house and take one big stress off your plate. You can start over, with or without him. You can find a better life not filled with debt and stress. Bankruptcy is often a huge relief to those who have been buried under a mountain of debt for far too long, it's a chance to start over debt free.
He has not been making good decisions, he cannot be financially responsible right now, so planning a way to borrow from one to pay another just doesn't make sense and doesn't solve your long term problem.
I hope you can work through this and find your peace somewhere in the solution. Anxiety will eat you alive if you let it.
Hugs and my prayers too for a better tomorrow for all of you.
