Hi merlin87tx - i would be concerned about your fiances dependency on this substance - its sounds as though he is self-medicating rather than going to someone with the expertise to actually help him. And this is what worries me. What is holding him back from going to a psychiatrist? He needs to accept that without professional help he isn't giving himself or his relationship the best shot at improving. I know i certainly wouldn't want to be married to someone who put drugs above their own health and happiness. He has to want to change and if it looks as though he doesn't have the motivation for this despite having you in his life and lot of other things to be greatful for, i would focus on you for the meantime and hopefully distancing yourself from him for a while will help him come to his senses. After all you've tried encouraging him to get help and stuck around regardless of how he behaved, so now i would try backing off for a bit and give him the chance to realise that you won't put up with his behaviour forever and that if he still wants you in his life he has to prove it. You're not his mother and you have your own life to get on with so please take care of you and remember we're all ears should you need us. Take care.
