How would you feel if your friends with benefits left you for a relationship if there were some feelings and it was completely out of the blue? I wouldn't say strong feelings, the kind of affections you would have for someone you had been dating for a few months with some distance in between, and it was exclusive but not serious. You texted regularly though and hung out besides just hooking up, and had been on actual dates before, but didn't want to commit because she would be graduating soon and your work schedule is very busy and hectic.
