thanks for your responses, i do have a habit of wanted to fix other people's problems. He actually said he might come and stay with me as i've moved from the area now, he sort of invited himself. We actually slept together before i left when i was using, but i've known him for years but that was the first time we took things further than friends.
I have just started my own recovery, so i know i need to focus on me, it's just so difficult to cut ppl out of my life, especially when he's saying i'm the only one he can talk to about this and that he can't sleep & stuff. I put him off coming here because the last thing i need is albanian gangsters banging on my door. I've said i think he should seek some kind of recovery but maybe i need to leave it at that now..
