Dear self,
You need help. Good work on finally manning up and getting it. Maybe you won't be such an asshole to the next girl you date now. Better late than never.

ps. you can't date her again til you're a better person, despite her wanting to be back with you. this is for the both of you
Dear Ex,
I'm sorry I was an asshole. I won't be that guy again.
Tango
