My boyfriend is in rehab for cocaine abuse.. I need some advice?

I’m 18 and I’ve been with my boyfriend for 2 years now. I’ve been through a lot with him and I could never imagine being without him. He broke up with me a few days ago for really no reason at all. He called me last night and said he’s just been having weird feelings about everyone, even his father. He said he doesn’t want to end up hurting me if he goes back to drugs.
I really love him and want to support him as much as possible. Is there any hope for him? I pray every night that he’ll be strong through all of this. He gets to come home in 2 weeks and I’m scared of whats going to happen. Is there anything I can do to keep him away from the drugs? I’m so scared..
