How typical is this?

Had a plate last year, turned her down when she wanted a relationship and she eventually got into a relationship with some fag. She now “hates” me. Even to this day I catch her staring at me in gym, practically breaking her neck to look back at me in the halls in college and coming up with ways to get me into conversation. Is it likely a girl like this will try come back to me after what I “put her through” (lmao)? And do you even accept plates who have previously broke?
