My ex is a goofball

Tell me how this girl i broke up with showed up to an event i was at (my friend was DJing there) and very obvly started making out with some random as soon as they walked in xD 

I saw her make eye contact with me tryna see if i was bothered…just proved to me i made the right choice. The fact shes immature enough to think id care was the best part of the night by far
