Strange situation here, my mother and father are paying for a large portion of the wedding, as are my fiance's mom and stepdad. His father and stepmother are very well off but have announced they will pay for less than half of the rehearsal dinner since 'most of the relatives are on his mother's side.'
Since his mother and stepfather are being so generous I want to include them as hosts on the invite but I'm worried leaving off his father and stepmother would offend them. However it also seems unfair to include them when they haven't helped as hosts equally. My fiance has no clue what to do either. Help!
