We're 3 good friends, been friends since college, been on holiday together etc.
1 is getting married today, me and other friend RSVPd 'yes' and we're happy to be each other's date as wedding budget mean friend's partners aren't invited.
Friend's mum is very ill in hospital and she's text me this morning to say she can't go to the wedding.
I know I should go, the only people I know are her parents.
