What does it mean when your ex stares at you a lot?

It means he is still concerned about you and what your doing. He wants to ger your attention but he doesn't want to make that move.in my experience whether I got broken up with or broke the guys heart they always come running back. Just don't act like you care about them & if you want them back they'll come back. But don't forget an EX is and EXample of what not to go for in the future :) good luck
