I'm a 34M and, the older I get, the more I avoid family gatherings.
I'm happy going to anything that is about my immediate family, but I find other relatives (cousins, aunties / uncles) increasingly difficult.
I've always been seen by family & relatives as being quite childish for never having been in a serious relationship... and *everyone* except for me is married and has kids, all my cousins do and I feel like the odd one out.
I moved to another city and haven't been to a family gathering in years (unless its for my parents or sisters).
Recently my cousin invited me to her wedding and I can't bear the thought of going. To make matters worse there'll be a few people from my school there who never used to particularly like me when I was younger (because I was shy / quiet).
Would it be wrong to simply RSVP 'no'? I feel bad but, I doubt it'd be a massive loss to my cousin either TBH
