Advice on what to do?

My boyfriend does drugs and I recently just found out how bad it is. Of course I don’t approve but I also don’t wanna leave someone when they’re going through this.

Right now, we’re at the paranoia stage of using. Does anyone have suggestions on how to help with it? He swears there are people looking in the house, talking about him and hanging out in the back yard… but there isn’t.

And any advice on loving an addict and what to do with coping with the heartbreak of it would be greatly appreciated
