Left without a date, Haleigh fortunately didn't have to resort to being a 17th wheel (LUCKY).
It was then that Haleigh's 5-year-old cousin Bentley stepped in. He is kinda mad at me because he says I threw him under the bus,” said Haleigh.
My bet is it has to do with him being embarrassed about dating you after your history with his friend.
He might be afraid that his friends would make fun of him for having relations with a girl his best friend dated, or he might be afraid of upsetting his best friend (even though the friend has moved on).
So the question now is if you are actually OK with it not being a relationship or if you are going along with it in hopes it will turn into a relationship.
