You absolutely did the right thing. You were looking out for YOU and you did what you needed to for your own well-being. No matter what your boyfriend decides to do, know that it has nothing to do with you, or his love for you, or wanting to jeopardize what you have together. He has a disease and he needs help and he has to decide when enough is enough. BUT, that will not be a reflection on you!!!!
I know you're hurting, but be proud of taking that first step. You are strong and you will be ok, no matter what happens.
Hugs,
