I know what i should do but i just cant do it?!?

This is such clic abuse behavior, he gets you away from all of your friends and family so that you feel like hes the only one that you have. He contols what you do and wear so that he makes you think your un attractive, all of these things are so that he can keep you even when you want to leave, and if he has anger issues all I can tell you is get out and get out fast because he may hurt you, I know you may think he would never do that but he could. And once you get out never speak to him again if yuu leave something with him, buy a new one but dont go back and get your number changed he sounds like hes no good
