Search Results: should i leave him drugs

So I dated a guy who put me through hell...
We moved in together after a break up because the lease was already pending. Found out he got a gf in another state. I told him he had to tell her the living situation or I would. He refused. Two weeks into living together he told me he was falling in love with me. I told him that he shouldn't say another word until he breaks up with her, if he chooses to do so. He said he wanted to in person, and she had bought him a flight.

The day he flew out came around. I brought him to the airport. He spent a little less than a week up there and she found out about me in the midst of the trip. Drama.
(I wasn't "with" him like that. She just knew I was his ex)

Anyways, he comes home. Doesn't want to talk about it. Calls her names like a child and apologizes for leaving me.
Yet he remained in contact when it was supposed to be me and him only. I got fed up with his lame excuse and said either she is pregnant or gave you an std, which is it?
Ends up she was pregnant.

Drama.

So I had no place to go and he refused to move up north with her and back home. I saw him fall apart. My name was on the lease. He told her that I wouldn't let him take his name off the lease and was holding him there. lol I even asked her to take over the lease so they could start their family, no.

A few months past and I told him I had to move home and he had to move with her and at least try it. He was about to be a dad. He eventually took on the idea. Prior to his leave he got a drug possession offense in my car. <20g marj. nbd. don't insult.
So we knew we were going to have to meet again soon for court. I wanted to help and make sure he was good.

His girl bought him a ticket so he didn't have to see me at all but in court. He still saw me. He lied about the ticket and had all his things packed to leave her and be home with me. I didn't know. On the way home, I drove, he lied about the flight, I got into an accident.

Updates!!!

Would you be with them and help them get clean? Or leave straight away?
Unfortunately my bf of 5 years has struggled with drug addiction I see himself dying slowly every day :( it hurts me so much because before this started he was healthy now he looks sick. I don't know what to do? I've tried everything and nothing's working out

The worst part is he has a little girl and she keeps asking me "why is dad sick?" "Why is dad sleeping all the time I want to go to the park" and I'm just speechless. I always tell her "dad is going to get better soon, we are all trying to help" :( then she goes to her room. I'm crying as I write this I know I can walk away from this forever but I do love my bf and care about him a lot I hate seeing him hurt himself. Should I walk Away?
