2. If the feelings between two mothers are the same, it is the same to invite two people to go on stage together, or they can be arranged in the same seat. After all, after all these years, there will be no barriers. If two people still have conflicts for many years, try to sit down and talk at two separate tables.
There is a problem with stepmother not going to the wedding;
1. If the stepmother doesn't attend the wedding, she may feel embarrassed to appear at your wedding with your real mother, so she wants to quit and leave this family game to you to face with your parents.
This is also a more rational approach. After all, due to the special growth environment and special family composition, there will be many guests on the wedding day, which will inevitably lead to people's discussion. If so, maybe everyone will reduce some discussion.
Another possibility is that the stepmother doesn't attend the wedding, and relatives and friends at home know about your family. If the stepmother doesn't come, some people may think that they have a bad relationship with their stepmother, and so on.
