I have two friends. Both single 1M, 1F.
In our group we quite often invite one of the others to be a plus one when needed and usually we're all happy to help.
This female friend has a big thing about male friend. I know because she told me.
Male friend is much more interested in her sister
I know this because he told me. He does have an idea about female friend's "crush" but she hasn't told him anything outright. Female friend doesn't know about the sister thing.
Anyway she has invited him to a wedding, which involves lots of travel, a four day trip in all.
He's unsure, but I think will agree to go. She's thinking this could be their chance to get together.
Maybe it is and they'll live happily ever after, but from what he's told me, that's unlikely.
Would you urge caution in female friend or stay well out of it?
