Thought help: I thought I was over him but tonight when I seen he has a new girlfriend all those feelings came back and I’m kind of feeling hurt. - Help.com

You just need time to wrap your head around things. Sometimes it takes a longer time than you first thought.

Seeing him alone would not have evoked the same feelings as seeing him with another girl. Even though you were not compatible with him, there’s that animalistic jealousy because you see him with someone else. That’s the primitive part of our brain reacting to that . . . and the wistful “What if?” we ask ourselves after experiencing a loss.

Get a new boyfriend he can see you with! ;-)

It always hurts, I don’t think that’s something that ever gets easier. The best you can do in that situation is stand up straight, shoulders back, smile and remind yourself you’re better off without him, perhaps a quick mental reminder of why you broke up. Wait a legitimate amount of time so he doesn’t think you’re leaving because of him and then get out of there. Those feelings are easy to fall prey to but they’re not reality, presumably there were an equal amount of negative feelings that precipitated the break up. Congratulate yourself on moving forward, even if he’s not a bad person sounds like you’re not good together. By default you can’t be in a good place and with him simultaneously, and since a good place is the best place to be, then standing next to him in her role isn’t something you want anyways.
