I have a daughter from a previous relationship. We were never married, but I am close to my ex's family (parents, sisters, and even grandparents). I am not close to my ex, and my daughter has an on and off relationship with him, so I will absolutely not be inviting him. I am wondering if I should invite the parents and sisters to our wedding. I've considered them a part of my family, and vice versa. My daughter's grandpa has even called me his daughter-in-law on occasion. However, my fiance is on the fence about it, and his family has gotten a little miffed in the past when they have heard me referred to as the 'daughter in law' to my ex's family.
Any advice on the best way to handle this?
