Hi!
I don’t think really you need to panic about your safety as such, drug addicts aren’t bad people, if he’s been normal for years chances are he’s been using the whole time so I don’t think he’ll all of a sudden become aggressive. People use usually because they’re self medicating – I’ve never met an addict who isn’t using for a reason.
I think you should continue to watch him and see how much he’s doing it and wait until next month when you move so then if he does become horrible you can go back to your parents.
My boyfriend is an addict but he’d never lay a finger on me / my child… I just think he will lie / manipulate, say you’re crazy, say that it was just the once etc.
Could you work through it with him and if he accepts help will you stick by him? You have to be ready for relapses though – as it’ll happen.
Always here for advice! X
