all my friends have bf and I have no one to talk to

title. basically they all got bfs from diff schools. I have zero dating experience or anything, we’re seniors btw. I’m so happy for my friends and love seeing them in love but esp during school dances I have no one to talk to. I don’t know their bfs and it’s akward and I don’t want to third wheel. last school dance i hid in my car. my friends aren’t purposely ignoring me they just want to spend time with their bfs who only know them and i get that. I just can’t help but feel left out. Ik it’s no one’s fault but idk what to do
