The last thing you need is a guy that lets you do Meth and Pills and throws a phone at your face, regardless of the circumstances...
You need to know you should be devoting more time to sorting your own life out then to his. You need to go to the local police department at which you made these accusations and change your statement.
The catch is, they might listen to you, but if you have a history of Methamphetamines they might not... You need treatment and you need new direction, and it seems like a guy that throws a phone at your face while your high, is standing in the way of you changing as a woman.
Its sad to read this because some woman are intimidated into loving their partner, and that sounds like the case here. Sure he's lovely when he's calm but when he's angry and your high it compounds things and may lead to a really dangerous confrontation. Get out and get clean and maybe the police will think your statement is credible but bottom line is you need to sort yourself out and that includes becoming an independent woman, un-reliant on her man!!!
By the sounds of it, you need some serious help and he deserves a little time! But if you keep to your current lifestyle, then you deserve to be behind bars as well. Get straight, clean up, and make amends!
