I have been having this issue for awhile and its now has come into a full on fight between my fiance and myself. His family has 4 tables (40 people) my side has 2 tables (20 ppl) most of those invited on his side are family friends and we are two very different cultures (polish and Iranian) my mom asked me yesterday how many each side has in tables i told her the number and she lost it.. she was very upset she feels she is the minority. She feels it will be awkward for her as we will have persian music and the entire venue is mainly persian she will feel out of place. His mom keeps inviting more people without even asking us increasing this number. My parents dont listen to polish music so i cant add that in.. i think they just feel really out of place. Im really in the middle,. invites are out so we cant dis-invite anyone. I suggested that we can make it more neutral if we only had English music as everyone there will know it,
