Last night my girlfriend ended things between us, 3.5 years. It wasn't either of us, I guess she has some issues to deal with at home and I'm attending a new school. Never felt so weird before, figured I only had a few choices, anger, sorrow, or acceptance. Taking the acceptance route, I sent her a message and told her I'll still talk when needed and that I'll miss her and had some fun times, I really will miss her...
being newly single is weird, but eventually you get to the point that you become comfortable with it and it's fun.
well it might not always be "fun" but the cool thing about it is you only have to take care of yourself and it's very liberating once you get past the phase of missing your ex and grieving the end of the relationship.
