My DH is an introvert and does not like social situations at all, especially so when there will be large groups of people present that he doesn't know/know well.
I am quite outgoing and whilst I am a bit of a home bird, I don't turn down any invites!
I have grown used to now being the only one of my friends who never has her partner accompany them to weddings, parties, christenings etc...
It used to really annoy me and make me think he looked rude but I am more understanding now that he genuinely gets very uncomfortable in these situations although it does get me down a little when I'm the only one with no partner at these big events!
He comes if there are just a few people and I often find myself wondering what the problem is as his flow with conversation is better than mine on these occasions! He is shy but I've never seen him come across that way to other people iyswim.
Does anyone else have a partner like this? Other than just nipping in my house to pick something up or for a quick brew, most of my friends only met him at our wedding!
