You haven't talked to Damon since 3 days.
You had a fight.
It was about him being insecure about you loving Stefan. Because Stefan always get the girls in the end. And it annoyed you. He may get all girls but not you.
As he kept bringing up this topic you fired back with being insecure about Kathrine. He had feelings for her and now that she is back yous te the one feeling insecure. He got annoyed with it and stormed out of his house.
Since then he kept blocking your calls and you kept blocking his.
You were going to the grill when you heard him talking. With Kathrine.
Kathrine "Bad day?"
Damon "bad century" *gif*
You just walked away.
