Quick question for people who value their friends

So one item of mine went missing, i didnt noticed not until i was gonna use it. My friend borrowed it for a pictorial, she did wore it at first but the pictorial had outfits there so she switched her outfit and now mine is missing. She said I got it back but as far as im concerned i didnt well it would be here in my closet right? (No i did not use it after the event, the other outfits they borrowed are here). Went and asked her about it and she just put the blame on me, i said to put it behind us since its been long gone i mean cant do anything about it dont want to argue over this BUT she just fcking said "aw" no nothing just that

Am i being a btch for getting mad at this, i think im being petty idkk, wanna talk to her about it since im very vocal with my feelings but idkk
