possible bipolar husband drug abuse mental

I have been dating my husband on and off for 7 years and married 4. he has had friends in the past that used drugs. I didn't think he actually did until I found out this year. He is on cocaine & anything he can get a hold of. He also has an extensive history of gambling flirting with other women claiming harmless as it's a game, jealous and impulsive. He has even taken my wallet and hit me drunk when I have tried to leave. one time I did because he said he wanted a divorce and took our only vehicle that was in my name, he got mad. I tried to make him jealous at this point and told him I liked someone else bc he was acting as if I didn't exist or c ared he asked for a divorce then claimed he changed. Then I came back he had spent all the money we had & our joint income tax. I do not know what to do because he doesn't see that when he does the drugs he is manic. He will say things he doesn't remember. He has even talked bad about me to friends and ppl. We work with behind my back manipulates everyone like it's a game but tells me he loves me and he wouldn't do that to me. I work with him. Everything is in my name & due to him gambling & me having better credit. I recently told him we need separate money because he is irresponsible. I had to hold the spare key in a safety deposit box on the 60,000 vehicle in case he doesn't pay the note, he got angry. I asked that we get accounts that we both can both see the balance transactions etc. for savings but are not joint. He now hides money & makes me split bills as if we are roomates. We also have an account for bills and when they are due 1 week before I'll tell him and well come to an agreement then when they are paid the way We agreed he gets mad and says that I'm stealing his money when he can read the statements from the bank. I have lost all interest in sex & he accuses me of cheating . I have to do all the housework, he does nothing around the house. I told him i was tired and he says I am and good for nothing. We work on the road so we are legally staying at his mom's still. He still has an account with his mom. She manipulates him to borrow money all te it's ridiculous. She is self employed making 900 a week at a shop. Only bills she has are house note and insurance car is paid off. Itold me i been tires and sorry that i do nothing dor him. im at my witts end.
