Fiance not invited to my cousin's wedding
I recently recieved an invitation to my cousin's wedding, and was surprised to find that my fiance was not invited. In fact, I was lumped in with my parent's invitation (which in my mind is reserved for children). A little background, I am 26 years old (a year older than my cousin who is getting married) and have not lived with my parents since college. My fiance and I have been dating for over 8 years, and recently got engaged in the beginning of December. We have also lived together for the past 4 years. Although I am not particularly close with my cousin anymore, we were very close growing up and my fiance has met him at least 3 times. Before I recieved the inviatation to his wedding, I had already included him and his future wife (who I've never met) on my wedding guest list. Also important to know, they are both Italian and have huge families so I know the wedding is not going to be small.
I guess my question is what would you do? Decline the invitation or just be the better person and go to the wedding? I figured his fiance is the one probably doing everything and maybe it was an oversight? Still, I am a bit hurt. I know people will be asking where my fiance is at the wedding, what should I tell them if I do go? As I've been making my own wedding guest list I always ask my fiance if I'm unsure about any of his family's relationship status (or I just use facebook haha) and I guess others just don't do the same.
