One of my ex-girlfriends considers my parents as surrogate parents, essentially, and her children treat them (and call them) grandparents. I dated her while I was in college and the weekend I went home to break it off with her she left her house crying and was being comforted by my mum before I got home myself. She needed their support so I drove back to college. That was over 20 years ago.
How freaking long did you guys date?
