I embarred myself in front of my ex! please help!?

By you running would make him think its weird, I personally wouldn't care if i walked up and seen a girl doing that (Thats how men are) but by you running would make me thing "Wtf??" and actully think about it more. All you should of did was laugh with him and their you go it wasn't as big as it seemed.. In my opinion. Next time you see him just joke about it
