I have really really bad anger issues, when only to my boyfriend . I'm such a rude bitch. I feel bad for my boyfriend sometimes. Whenever he does something wrong I flip out and say really fucked up things to him. I dont know how to change :( I'm surprised he hasn't left me yet. Or moved out, with some thing I do. Ugh.
