My fiancée and I are confused about seating his parents boyfriend and girlfriend? His parents are divorced but remarried but are no longer with his stepparents. They are both legally married to the stepparents but both have significant others? Now his dad is 60 and decided to date this 21 years old and had a baby with her. He and this young girl has been together for a little over a year and my fiancée or his siblings have never met her. His mother's boyfriend is legally married to someone else and has been around for about 8 years. Both parents wants their boyfriend and girlfriend to sit in the 1st row with the parents and walk down the aisle. My fiancée says no and that they can sit in the row behind. We both feel that the stepfather who was in his life and still is for 17 years and his stepmom who was in his life for 21 years and still is should be in the front row with his parents. As I stated previously, His mom is still legally married to the stepdad but has a boyfriend and his dad is legally married to the step mom but he has a girlfriend too, which my fiancée never met. We both think that its a little disrespectful to the sanctity of marriage but to each is own. Where should the boyfriend and girlfriend sit? Please help!
