Saving Grace
As a wedding guest, the best part of the entire thing is the celebration and the dinner and drinks. When the OP’s aunt left her abusive fiance at the altar, things got pretty awkward for the families and guests waiting for the ceremony to start.
Thankfully, the bride’s father took the reins and made an announcement that there would be no wedding but everyone was welcome to stay for dinner and drinks on him. What a great save! Besides, the fact that the bride managed to escape a bad relationship and a potentially awful marriage deserves a celebration, don’t you think?
