Groomsmen
The groom asked his sister-in-law to be one of his groomsmen, despite it being not so traditional. All the same, the rest of the groomsmen didn’t mind in the least. From there, things started to go south between the bride and the sister-in-law. Even more than before.
The Fiance
The future bride was somewhat problematic. A couple of weeks after the groomsmen were chosen, this person got a call from the groom saying his fiance wasn’t comfortable with the arrangement. Especially the stag night. We should mention that this person’s husband was going to be there as well. In any case, the fiance worried that a woman being there would cause problems. And so, this person just let it slide rather than cause drama of any kind.
