I'm leaving my husband

I'm really taking this into consideration because I can't deal with this anymore. Before we gotten married he was getting a job planning on going to school and doing the right thing. After we got married he started back selling drugs heavy, and doing drugs as well. Meanwhile I worked 50hrs a week paying almost all the bills which accumulated to about 2500-3000 a month and he only can afford $800. He crashed my car and always coming up with a new bill that has to be paid. Now I'm his wife so I'm constantly trying to encourage him and do things for him to keep him happy. But I can't anymore. He just sat here and told me that it's always something coming up that needs to be fixed. I told him maybe it's time to get a job and he really just brushed me off. I'm leaving next week to my cousin house and I'm not telling him of course I would have to pay rent at two places but it is what it is. I don't know what to do. This is all that I can think of that will hopefully bring sense into him. If not guess we will file for divorce.
