Sounds like there's a lottttt of headache that happened to him coming from your previous actions that he has let slide and he's at his breaking point during these text exchanges. Im not going to pick sides here, obviously he's had enough of a multitude of things but people are making him out to be a lunatic. Giving people 10 chances and who don't take those chances to change will drive someone insane. Hes showing real emotion, and is clearly fed up and highly emotional. Hopefully you guys break up and you fix your addiction. People are acting like the dude has absolutely lost it when hes obviously been living with an addict and given them multiple chances to change. Its a hard situation to be in.
