Girlfriend using another guy clothe?

Imagine im in a LDR and my girlfriend went to a camp but didn't brought warm clothes and , its like raining and cold there , and she asked a friend a sweatshirt , I don't know how long they are friends but i asume its like a childhood friend or something , is it ok , do im getting jealous , like i talked to her about it in my opinio is dirispectful and uncomfortable but maybe in this situacion is a slide , but the thing is she posted a close friends storie with the sweat and that triggered me , pls let me know your thoughts people
