It sounds like you did deliver an ultimatum...my question is are you going to stick with what you said? Our own behavior is the only behavior we have any control over....
I am facing a very simular situation right now...I did not say he had to go to rehab all I said was that he cannot use drugs on my property or in my presense. To my knowledge he has not used since I last blew up.
The main thing is that I am the only one I have control over. I can put my boundries in place and it is up to me to keep them enforced. It is up to me how I react or do not react. It is begining to feel like for me I need to take responsibility for my feelings and behaviors. I hope I can keep the focus on me and keep my hands off what my H is doing.
