I will begin by saying that my FH and I are paying all costs for our wedding. My mother passed away 2 years ago. My father and her were separated for years but never divorced. He remarried last September. I did not attend the wedding. I met his wife once and have never had a conversation with the lady. He informs me today that I should call her to discuss the wedding colors. I am not sure why I need to do this. I advised him that she can just wear something to match his vest and tie. I then realized that I only ordered corsages for my FMIL and grandmother but from the discussion with my father she is preparing to be a part of my wedding. I did not even think of her when I placed the order with my florist and feel no obligation to include her. My FH feels like I should order her one because she is my dad's wife. I feel no obligation to do so. She is not a mother to me and we have no relationship and I am ok with that. What do you ladies think?
