yes it can just go away, it is called life and you are the one hanging on. people have the need to feel loved sometimes and like when people look up old flames, they wanna see if someone out there still loves them, they crave being loved, they don't look up old flames because they love them. it's a selfish action. they wanna know someone still loves them. maybe she is feeding the need, but it's not because she still loves you, she just doesn't want to feel forgotten , unloveable, and infatuation can fade as quickly as it came about. the day she sees you sitting on the toilet pinching off a couple nuggets her illusion of you being perfect can fade instantly. you are a real human and not her hero any more. that's the breaks, your only consolation is that one day you were on top. good luck.
