Most Helpful Girl
Open lines of Convo is One of the Most important factors in any New or Old relationship. And now that he has pushed a button on his own to let you know the Reason why this had to End, perhaps is the time to talk to him and do This... Face to face.
All you can do is try and explain yourself and find out how you can make things better, should you both get back together. If he tells you "Not right now," then respect his wishes, and tell him you hope you both can be friends for now and "Maybe later we can try again."
Good luck. xx0
