Well the only other thing i can think of.. ill tell you how my gf best mate.. how her bf and what he did on coke.. he unscrewed everything eletrical in the house thinking hes being watched.. he accused her of sleeping with asians… and he found an asian passport of a guy in the house.. he showed it her and it was a cut out of a kids book of a made up play passport…
She came home and he had a machete on him in the house saying people are coming.. no one was obv..
Then he was missing and he was seen and pics uploaded on fb.. of him in someones back yard no socks or shoes on drinking water from a hose pipe. He got sectioned after that. Too much coke and no sleep makes you have a mental break down. You recan it could be that? If hes not enjoying it anymore. Its just gonna get worse.
