Meth, Married, Abuse and no support!?

Please dont judge just help me I am with this man I have been with him a lil over a year, things were bad from the start a lil while into it i foung out he was married and I decided to stay anyway he told me he was getting a divorce bla bla bla still no divorce and come to find out he still talks his WIFE! I was fed lies and totaly deceitful this man lies to me straight face. I know FACTS about a few things and nothing is changeing. I am the only one who works and I support him and his habbit now I had suspicions about his habbit little bags and what not now i found a pipe a meth pipe, he denies any use yet i know for a fact! I am crazy I know I dont know what to do! I think he is a binge user I still cant believe I am allowing all this to happen to me, now the abuse he hits me not all the time but it happens he has done some pretty bad things to me, I never saw a man so eager to hurt me physicaly. He dosent work he dosent do NOTHING! I dont know how to ket go! I do care and love him! Why am I so stupid!?? Please tell me I need help i know i want counsling i lost me and my self worth why am i so weak?? HELP ME anyone I dont know what I need. This man cant possibly love me the things he does and says to, but at times he is the perfect man I dont know the difference any more between him being high i think he is nice when he high and mean when he is not so this means he only loves me when he is high! I totaly hate myself I am ruining my life i know i should leave its not so easy easier said than done.
