annoyed!!

I'm so annoyed and don't have anyone to vent to so here goes.. here's my story.

my boyfriend and I have been together for going on 4 years now. he's always smoked pot, I personally don't smoke. well in 2015 we hit a bump in our relationship and split up. this girl who was supposably my friend went behind my back and gave my bf meth. he got hooked. I've used here and there in the past but we ended up getting back together and we we're heavy users. in October of 2016 we got caught up and got raided. luckily for us didn't leave a messy trail or anything like that. since then our charges have been dropped and it was pretty much an eye opener. we stopped doing everything! I have been sober for going on 11 months now. but I'm starting to question my bf. he keeps accusing me of being high ALL the time. I'm getting sick of it. I come home from work and start cleaning whatever and I'm "high" I literally can't do anything without him asking me if I'm high. it's starting to cause a big problem in our relationship. I'll ask him if he's been doing and he gets so mad that I would even think that about him. I'm just so lost right now. any advice?
