Love or limerence?

Oh! the wilted flower between the pages of my book, 

Ain't it pretty, familiar yet sad,

Like your feelings for me?

My longingness to see you at the other side of the station,

Oh look, then running to your arms will end as a dream may be!!

Your footstep is still here you just didn't write or call,

Were you running from me or did just you run out of time?? 

Still, I waited at the door hearin' silence screaming goodbye after all. 

"If this sadness is only in my head" 

When I opened my eyes would you still be mine??
Pieces of the puzzle are missing to conclude, this is your final inference.
20 and 5 are close yet far, so tell me straight "Is this love or just my limerence??"
