Hiya hope your OK. I’m the same as your bf but I am now 7 weeks clean from coke. I have finally joined CA anonymous and its helping me so much.
Anyway.. If he doesn’t want to quit, it’s just going to carry on and on and get worse. One of the biggest problems with coke is the come downs when it’s wearing off, it sends you depressed and suicidal for days. If he is doing this 2 to 3 times a week. He is never gonna be giving time for his brain chemicals (dopamine, serotonin) to get back to normal. So this is why he probably is nasty.
My opinion is.. You haven’t been with him long, think of your self and move on. He needs to work on him self and recovery if he wants to. Don’t get trapped with a kid and a vicious circle of lies and using. Hope this helps. Feel free to ask me anything
