So my fiance's mother remarried about three years ago to a man will already grown children that neither me nor my fiance really know. They approached my fiance with expectations that his step-siblings would be invited to the wedding even though we don't know them. My fiance told them that he would rather not have them at the wedding, as it would expand our guest list beyond our budget and, honestly, just cause they're step-siblings we felt no need to include them in our wedding list since we have no real connection. Their response was to offer us more money to cover the additional guests, to which my fiance said no.
Having made our stance clear, nothing was mentioned again until the tasting when my future father-in-law said something about how his son wouldn't like the food. Immediately, my heckles were raised as it was evident with that comment that they were still expecting us to invite my fiance's step-siblings. Now my fiance is too nervous to remake our points because his parents are already helping us out with the wedding. I, however, don't care. His side alone makes up about 65% of our guest list and I won't even have my own siblings and parents there due to differences of religion. The more people added that I don't know, the more overwhelmed I become about being comfortable on my own wedding day, especially given my anxiety issues. Neither of us want these step-siblings invited, but we're not sure how to re-approach the topic and lay down our wishes without offending his parents and solidifying our decision in their heads. What should I do? Should I just cave and let them invite who they want to spare their feelings?
