Hi! My brother-in-law is getting married in August. My MIL and I do not get along. She just addressed the wedding invitations and low and behold, ours came addressed to my husband and 4 year old daughter - NOT me. I think this is incredibly tacky. I have no beef with the couple getting married, and as far as I can tell, they have no beef with me. I don't want to make my husband miss his only brother's wedding, and my daughter is actually in the wedding, but I feel like my husband should either politely decline (which he has offered to do) or the couple should intervene or SOMETHING should happen here. What is the correct way to approach this situation from an etiquette standpoint?
