Boyfriend confessed coke addiction drunkenly

I always had a feeling but he would deny it and warp things for the 9 months it went on for. I kicked him out and said he should feel shame and guilt for all the lies and the manipulation and now I feel conflicted I’ve been there for him for 2 years now I can’t imagine ever losing him and I would love to help him through it he claims to be 2 months clean and never wants to touch it again what am I supposed to do.
