I know you will all have some great input for this, so I'm throwing this out to the community. I was recently invited to a cousin's wedding. I myself am engaged, however, the invitation was only addressed to me and did not include my fiance (who I also live with). The invitation was a very simple postcard, with no response card to indicate that he even was invited ("We have reserved 2 seats" for example). This really bothers me because I feel he should have been included on the invitation and now puts me in the awkward position of asking them if he is invited. Also, my 21 year old sister was not invited to this wedding. I have no idea why, as she would not apply to the "no kids" rule or an outside circle as we are all first cousins. I feel like I should kindly decline attending this wedding solely due to these etiquette missteps. Am I overreacting or would you feel the same?
