My dad has been kind of a not so nice person lately, and my fiances' family ( brothers and sister-in-laws ) are helping us with wedding expenses too, along with my mom and other family members. Would it be wrong to say in the invites The families of blah and blah rather then Dad and Step mom: mom and step dad , and dad and mom invite you?? also since one sister in law is paying for invites and over 14 lines is extra????????
