Hi Kelly,
I don't know the history, but.....is your boyfriend an adolescent? Then I do understand the involvement of his father, doctor regulations, etc.
But....is he over 20?
If so, this seems a very tricky set-up for a lot of bitter resentments on his part, which matters for you only because he will dump his seething resentments on you, either overtly or passive aggressively, sooner or later. It is very very painful when the addict turns on us like a snake in the grass.
I am concerned about how very close you are keeping to a drug addict who at present is without any substantial recovery.
Please stay with recovering codependents, here or in meetings or both, so you can get help staying clear. Your welfare--physical and mental and emotional--needs to be your number one priority.
Right now he is breaking up with drugs.
He is not happy about it, no matter what he is saying, I would suspect.
So just be careful and stick with people who are savvy about codependents and addicts.
Stay strong. God bless. I hope for a very positive outcome for you no matter what!
