Imagine the feeling of getting someone to love you, only to abandon them and leave a permanent emotional mark on their soul. They'd never be able to get you out of their head, and the bad times would always pale in comparison to the good in their mind. They'd cycle between anger and depression, but they wouldn't really ever be able to hate you. Deep down, they'd really just want your love back. Anybody else they'd find would just be a replacement to distract them. Maybe that's actually the purest love of all.
Besides, a tragically romantic story of lost love is far more poignant and healthy for character development than a dysfunctional relationship where one is constantly annoyed by the other. Pinkfags understand that she did nothing wrong. The rest of you just lack maturity beyond "MUH FEEELS". This was actually good
for Spinel, now she's more grown up.
