Stalked and got myself upset

ok so i’m gonna sound crazy but idrc, my boyfriend is away at school and i’m still home bc i’m in hs. i trust my boyfriend and ik he won’t do anything, sometimes i stalk his friends that r girls on social media tho idk y exactly. like yeah i’m jealous of them, not bc they’re crazy pretty or anything but bc they get to see him sm and i don’t. but whatever i was on one of their VSCOs and there was a gif of like him and his friends in a bounce house having fun and he looked so happy and stuff and idk now i’m upset and idk what to do. i don’t think he would get upset if i told him abt me stalking her but idk. it just made me sad and like i wish i was there w him and stuff idk.
