Continuing to play those thoughts in your mind of whether he is a user or an addict is taking away the fact that he has been violent towards you and you've been hurt by his violence. It's easy to blame the violent on drugs and booze becasue I'm sure when he talked you into coming back he wasn't hitting, punching or throwing you into walls but the fact is cocaine and booze didn't throw you into a wall HE DID. Please get yourself out and someplace safe.
