So there is a long story with this but I need help and we are down to the wire getting married on the 27th. My fianc's parents are divorced. The mom stayed out of his life for 14 years and just popped up when we got engaged. She has talked to him twice in those 14 years. My fianc's grandma has basically taken care of him. He moved in with her when his dad was into alcohol. He has now rekindled his relationship with his dad and step mom. He doesn't want to offend his mom with this wedding and I can't stand his mom and think she shouldn't be offended since she hasn't been in his life and couldn't acknowledge me when I met her. Basically the problem is I think he should do mother son dance with his grandma but he thinks that will offend his mom. Also we don't know how to do the receiving line if we have his step mom in there and mom or if we leave his step mom out. His real mom knows nothing about our wedding except the day and time. She hasn't asked questions or done anything. She even ignore the bridal shower invite from her daughter my future sister in law. I didn't put her in the invite. I just don't know what to do with the whole mom step mom and grandma being a mom thing. Any help or suggestions? Thank you!!
