My family is really small consisting of no more than 20 attending my wedding. My FI on the other hand has a HUGE family with aunts cousins and great aunts. His mom wants to invite all these people who are her great aunts who I dont really know, we want our wedding to be no more than 75 people. How do I tell his mom that we dont want to invite those people, I know its my wedding but I also dont want a crabby MIL at the end of the day because her great aunts couldnt come and whoever else she wants to come cant. HELP!
