Most Helpful Guy
You have a bigger problem mister.
It sounds like you're mopey and depressed about the situation. I don't mean that you're unhappy about losing her. But it sounds like you are not happy with the loose ends left behind from how the relationship ended. While you may have both moved on, or aren't interested in each other anymore, your mind will always linger back to that loose end. I suspect you may have even had dreams where you two sat down and chatted with each other - saying the things you needed to say in real life - but never had the chance to.
I would probably suggest to get over your pride, arrange an afternoon and go to coffee with her to make this discussion happen and put your mind at ease so you can carry on.
