Same situation, except I'm a girl. Problem is, I can't put any distance between me and my ex. We're in the same class. Wonderful. -_-
or make sure a big fat kid sits in between so that way you can't see him.......thats pretty much other side of the moon in some instances.
What you need to do is forget her! Just see it as you passing off your old / used goods to a less fortunate guy
Idiots. OP already replied saying "time will make it fade away". What the fuck are you people doing still bumping this thread. Damn noobs.
Its normal for that feeling to occur, its all because at one time you two belong together and after the breakup even after a couple of years. there is still comparison, harmless comparison of why did he leave you or why you two broke up and hes with her now... its nothing just jealousy and envious pay no mind... if you have a new boyfriend too it wouldn't have felt like that. its most likely because you don't have someone rite now that you have nothing to compare him to but u compared yourself with his current GF. hope that helps. Feel better!
Like you said time will eventually make it fade away. However, it is perfectly normal to feel like this.
