Help husband crack addict!!!

I am a school teacher divorced with 2 kids. I met a  wonderful man last hear who I was not aware was a crack head. He has put me in debt 65k in credit cards. He relapses every time his own kids mess up, his son was caught molesting and raping a younger sibling. He relapses bad and wipes our account. I fixed his teeth,  gave him everything. I am pretty I think but I forgot because I cry every day, I don’t sleep, I have lost so much weight. I want to leave him but I know he will get worse.  I do love him but hate him also. Please help.
