bitch face

I don't have many chick friends, so when my boyfriends rugby team (or any friends of his in general) bring their girlfriends around I always try to be friends or friendly at least. I think my face is mean or intimidating or something because people never like me when they meet me. 🤔 I usually am shy but regardless, when I first approach my boyfriends friends, girlfriends (confusing I know) lol they never are sweet or interactive back? Lol how the fuck do I become more approachable!? I try and smile and initiate conversations, make people feel comfortable but NOPE! Nothing! Anyone else have this problem ?
