I don't know about this... I am not getting a good feeling. It's bad enough that the whole physical aspect to your relationship is very strange, and the possibility he is smitten with someone else, but the fact that he is a recent user (addict?) is enough to make me want to put the brakes on it all. Getting off the drugs physically is only a small part of the equation. The emotional baggage that comes along with it all takes a LOT longer to get over.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
