Can’t match my fiancé’s groomsmen…

I literally have no friends or close family. I am unable to even come up with one name for a bridesmaid.

My fiancé on the other hand is such an extrovert and has a handful of childhood friends that he would like to have stand by his side.

I’ve met and hung out with all his close friends, both male and female, but I don’t feel as if I’ve built a close enough bond to invite his female friends as my bridesmaids.
I’ve voiced my concern to my fiancé that I’m afraid I cannot make friends in time for the wedding. It doesn’t feel genuine to rush or force a friendship just to fill up spots for the bridal party. He continues to tell me that I still have time to befriend his female friends or make new ones and that I’m giving up too early.
I’ve pitched the idea that I’m okay with including both his male and female friends as a joint party and have them equally split on each bride and groom’s side. My idea was kind of brushed aside so now I feel stuck on what else to do.
It’s been an extremely lonely and embarrassing process…
