Some folks, on the other hand, were keener to give the groom advice instead of judging his actions:
“The fact that both the brother/sister-in-law and OP’s parents are angry speaks volumes about how they all thought that nephew was going to be the exception to the rule. I think OP needs to have a serious conversation with his parents about how his brother was crossing a line with him and also his fiancée by trying to guilt her into bending. If they continue to be angry about it, then he can give them a choice, either stop talking about it or not go.”
