Background: I have not used my first name at all in my adult life (I hate to be called by it for any reason), and FI hates his middle name. When I got divorced, I didn't go back to my maiden name because of my daughter and the fact that I had my married name for almost 17 years at that point, but I don't really want my ex-husband's name on our invitations.
Would it look strange to just have our first names on the invitations? We are hosting, and there will be no mention of families.
