After about two months of being apart.. you so happened to go to a house party with your ex. She was attempting to make you jealous.. in an attempt to get you back by making out with a bunch of strangers. She was quite desperate

You were standing over at the punch table- a bit tipsy but not bad... as your ex Elisa, was kissing someone on the couch- looking back at you to make sure you saw.. making loud noises- although they were heard to hear over the music.
