How to better understand this situation why the childish behavior?

[Petit Papillon]

Yeah dude like stop calling her, forget about those things - treat them like you had a fire at home and they got burned there. Leave this girl alone, even if she's the one who broke up, NC is NO CONTACT rule and you clearly make her break it because of such a stupid thing.I agree with Miso,she's a bitch to you cause she wants you to **** off,i'm sure she thinks this is the only way to make you leave her alone. She's the past, move on dude.

might she have anything else of yours you may need one day?

no/ not that i know of or can think of. I believe i have got everything of mine from her. it wouldnt matter anyways i wasnt using this as an opportunity to see her anyways. It had been weeks since i had contacted her before this and didnt plan on contacting her until i noticed i needed the book

No. There's nothing else to add. You have your stuff back, who cares how much of a snotty bitch she is.
