FH and I are newly engaged. We have both been married before so we are having a small wedding (25 guests). Our dilemma is whether or not to invite my aunt M. I will be inviting my grandma who is my only living grandparent. Now grandma lives with Aunt M. So to me it feels weird to not invite Aunt M. because I would be sending an invitation to that household. However, I am not inviting any of my other aunts or uncles. My grandma lives near my sisters and parents so they can definitely get grandma and travel with her (my family would have to travel to Florida from out of state). I don't have a problem with inviting Aunt M, I love her dearly and she is my Godmother, but I don't want to seem unfair since I will not be inviting all the aunts and uncles. In case it matters Aunt M is not married so it is only her and grandma in their household. Thoughts?
