It's a long story but when I got together with this person he seemed not to have any issues. After a few years it became apparent that he has on/off problems with drug addiction and gambling.
After the latest phase of getting hooked on a street drug called M-Kat he went to get help from the local pathways centre. The doctor there has been prescribing him methadone which he was taking every day. Then recently I found out he's started using again. He then said that he wants to stop everything and cut contact with his doctor. He said that he was going to give it all up but is still taking little bits of methadone. However, his doctor has stopped prescribing it of course because he hasn't been turning up for his appointments. He has been lying to his sister and lying to me about what he's really doing. His sister said that their parents are willing to pay for him to go into rehab but he won't.
I told him that he's never going to get better while he does this washy washy approach with the methadone but that's not what he wants to hear so now he's saying really hurtful things like it's my fault he's like this and that he doesn't want to be with me any more because I have children (he doesn't) and we can't do anything because of them. It really hurts that he would say this because all the time I've been with him he took a great interest in them and really appeared to love them.
At the moment I don't see him and I know he's not a good role model for my children. My parents have a codependent relationship - my dad is an alcoholic and my mum has spent her life propping him up. Even though I know this I can't seem to get out of cycle of having unhealthy relationships. I've had extensive counselling and fixed a lot of my issues but this seems to be a hard one to change and I don't know what else to do.
I find myself worrying about him all the time. OTOH I've wasted a lot of years on this. I know I need to leave, but I find it very hard to cut people off, friendships too.
Sorry this is so long.
