Activity for Lauren

So my fiancé and I have decided to have a small wedding. We’re looking at about 80 guests now instead of our original 170. We are having our wedding at a winery, so we decided that the minimum age to attend would be 21, except for our direct family...

So my fiancé’s best friend has a terrible gf that hates both my fiancé and myself. He expects us to invite her regardless (even though we’ve had a rule where the 4 of us can’t be in the same room). Do I really have to invite her?
