Dear Roger, I know you will never see this, but I wanted to say I’m sorry for everything and that I miss you… I know you moved on and you’re happier with her, but I still love you probably always will, I’m sorry I couldn’t be the girl you deserved or wanted, but I really tried, I know its almost been a year since the relationship ended but I just had to get this all off my chest, I still cry over the thought that I hurt you so badly after all u have been thru and u didn’t deserve that. I’m sorry… I love you and I miss you.. I wish u could forgive me but what I did was unforgivable and I understand that.. I’m glad we are still friends but u remind me every time I mention the breakup what I did. I’m sorry for what I did. 
Love your ex, J
