You and Ezra had a very healthy relationship. You never argued and always trusted each other. Because of that you went out a lot with your friends thinking he didn't mind it. As you started going out more he became more possessive of you and didn't let you go out. He became completely obsessed with you and didn't let you out at all. You had enough of it and escaped from him. He was the reason you made a band, you wanted to get him out of your head. You didn't think he would find you again.
