Why do toi think joy liked fabian when nina already liked him?

Joy liked Fabian because fabian and joy new each other for every long time and were best Friends and she fell in l’amour but they make a horrible couple any way.

1.because she thinks thay dated before nina came but it was just in her head
2. She doesn't like nina and to make her jelious she kissed Fabian at the prom and knew what she was doing
3 she barely became Friends with her in season 3 but nina wasn't there

She was jealous because she was forced to leave the school because she was the chosen one. She though Fabian loved her but when she came back, he was with nina. I think its because joy didnt think it was fair that she had the oppertunity to get fabian but she Lost it.
