Okay ladies, I need some advice. My fiance and I, along with my parents, are paying for most of the wedding expenses. My future in-laws are paying for my fiance's tux and the rehearsal dinner. My fiance's mom also is going to put together our silk flowers. These are the only expenses they are contributing to. The rest is split between my parents and us about 50/50. Should we include my fiance's parents on the invitations? I don't want to cause issues, but I also feel like they're not contributing nearly as much as the rest of us.
