I have a boyfriend but he is mentally abusive. He says if I leave him he will kill himself and cut himself last time I tried to, and now i feel really bad as I’ve started to develop feelings for a teacher on my college course and i fantasise about him daily, and rarely in a s***** way. I dont know what to do and I feel awful. I know I’m not good enough. To make matters worse I’m also developing a crush on one of my best friends. I really want to commit. Ive attempted before and I want to die.
