My fiance's step mom has offered to host our dinner, and she asked us for a guest list. We have decided to invite the wedding party, their SOs, and immediate family, and SOs.
Now. His biological mother DOES NOT get along with his father and step mother. I feel like she would be out of place there, but WE would like to honor her, and visit with her. We also don't want to make the whole thing uncomfortable.
What is the right way to deal with this?
