You could turn that into something positive. I was recently broken up with and I’m dealing with it by performing open mic comedy about it. Find something constructive to do. Your mind will wander and you’ll have something to show for it. You got it man. This community seems awesome for support!

How can we not pine for the one that we love after they leave ? Not an easy situation.

The fact that you want her to be happy is healthy. So is missing her. It’s not selfish. In time, you will meet someone else, and your feelings for your ex won’t be as pressing. I have loved someone I can’t have, and it sucks. But I know he’s not the only person who can love me, and vice versa. I manage it by keeping busy and doing as many social things as I can to increase the odds of meeting someone. Good luck!
