Sick - I know what your going through too. I think most here do or they just have not been exposed to the truth yet like you have. The whole drug culture if you will is so alien to people like myself. The lies, decieption, sex/prostitution/cheating it all seems to run hand and hand with addiction. You asked if he was cheating, either he was or he was working up to it. I think this was your HP saying you deserve better. Not every man cheats nor does every woman in this world. Infidelity can be a problem in relationships where there is not drugs involved but it does seem where there is an addict there is or will soon to be cheating. Take what you know and use it to help yourself out of this bad situation. Do prepare for the parade of excuses, blame and lies to justify his actions as it will be coming, on the other hand you dont have to listen to him explain, you can just hang up on him or shut the door.
