should I leave My husband of 7 years who is addicted to Meth?

I have been married to my husband for 7 years. I found out he was addicted to meth after we married, I have tried to keep this marriage together, hoping and praying that he will change. I’ve always thought that if I give him alot of love treat him good, he would change. But nothings changed. He doesn’t work. I work full time and in the process of starting my own business. I’m very successful as far as raising four children on my own, paying all the bills and jugling the kids to their sports activities. He has only worked a total of maybe one year total in the seven years weve been together. He does nothing for himself. I have gotten a restraining order on him, put extra locks on my doors and he has always managed to get back into my house, one way or another. After moving out of four homes hoping he wouldnt find me. I find myself exhaused. I find glass pipes in his posession, burned foil etc. Hes up at all hours of the night. We argue everyday? What shoud I do?
