Hi Mercury, I am quite positive about the future now but that wasn't always the case and I have had some pretty dark days, both with X and after we separated. But things do get better, just be willing to accept help and support from family/friends/MN.
I asked him repeatedly to find help but he was adamant he didn't need it and could stop on his own, his attempts didn't last long (I'm talking hours here) and the only times he went without was when he couldn't get any due to lack of supply.
I had enough of it then and told him, no more, it's over. That is when he contacted drug services and is now on a program. He has been following it and the staff there seem pleased with his progress, he knows to have any kind of meaningful relationship with the DCs he needs to give this up. Unfortunately, he is on a program that replaces the drugs with prescribed medication, so for me, I feel that theres not much change as the addiction has just shifted to another substance, the dependence is still there although he is more stable and money is no longer as much of an issue. I woulkd have preferred from him to reduce what he was taking until he could stop.
I am not sure about the legalities of access and/or SW involvement - there are SW and solicitors who use this site who could advise you or point you in the right direction much better than me.
In my case, I will not currently allow unsupervised access, this is because X is on a programme that involves a lot of controlled medication (methadone, diazepam, zopiclone and anti-depressants) This is a cocktail that is definately not condusive to being responsible for young children. He agrees with this so social services involvement has not been necessary for us.
I am so sorry you are having to go through this Mercury, and just stay strong, it sounds like he is still very much in the me,me,me stages and unfortunately addicts are inherently selfish.
Good luck and
