So my mom has already helped with the venue deposit, and buying my dress. She hasn't said it, but I know that she will help with more, but my parents are divorced and my dad hasn't offered any help, nor have my fiancé's parents. His most likely won't offer any help. I don't want my mom to feel like we didn't give her credit for her help on the invitations, but I don't know if it's considered rude to leave out other parents.
Have any of you run into this problem? Opinions or "proper answer" greatly appreciated!! Thanks!
