Soul.Searching Hard to say really as I am in another state of mind now than before the break up. If she talked to me calmly and sincerely and conveyed her hurt feelings without "attacking" I think I would take it upon me. At least I would try to change it. People differ though.
It's a hard thing to balance. You don't want your mates seeing you as "that guy", and you don't want to hurt your W. Suddenly you feel caught in between, and W is nagging while your friends may not.
I started changing a bit, but sadly like many others, things had to go apart completely before I woke up and saw things more clearly.
