Last night FI and I were putting together our guest list. We had some serious numbers to cut back on from the list that he was originally provided from his parents to keep the number around the 150-165 that we were planning on. On the list that was cut back his Aunt remained. Now here is the tricky part- his aunt got divorced from her husband about five years ago. The husband is FI uncle by blood (FI father's brother). Uncle will be invited to the wedding and is someone that is a part of our lives and we see frequently. Aunt is living with her new boyfriend and has been for the past few years. FI wants to invite the aunt but not the boyfriend. My instinct is we cannot invite her without her SO. Also, this aunt and uncle have three (adult) children together and we were not planning on inviting any of the cousins to help keep numbers down (large families on both sides).
How would you go about this situation? Do you invite the aunt? Do you not? It just seems wrong in my mind to invite the x-aunt but not the cousins... I don't know I may be reading too much into this. Your input is appreciated!
