Only you can make this decision, but I have to tell you that you are playing with fire. You have read my recent thread, "Fourteen Days." Our relationship has been an expensive roller coaster ride, filled with drama.
I started seeing my ABF shortly after he got out of rehab. I wasn't very knowledgeable about crack. I thought he was in recovery and really wanted to get well. He seemed so sincere and convincing. During a period of a year's time, he went back into rehab or detox at least five times. He always made a point of telling me that an addict never knows when he is going to relaspe.
If I had all this to do over again, I think I would have run the other way. At least, go into this with your eyes wide open. Keep reading the posts and see what you are up against. This is an illness he will probably fight for the rest of his life. I pray you will make the right decision.
