Can You Blame Me??!!?!?

My friends all ticked off at me because I'm not happy or supportive of her new relationship!!! Here's the catch she's dating the guy I've liked for 3 years.......I told her 4 days ago about my feelings for him I come to school the next day and their dating!!! Apperently after I told her about him she searched him on facebook thought he was hot and decided she would "make sure he's a good enough guy for me" Can you blame me for not being supportive of their relationship?!?!
