Asked my step son in law to be best man but he unfortunately declined. Fair enough as he was best man at a mates wedding and found it very stressful so would rather be able to enjoy the day as a guest (his wife is the only bridesmaid).
I don't feel inclined to ask anyone else as it will seem very 2nd best man to me. So the question is will it look weird and a bit billy no mates if I don't have one?
