So my FMIL is very upset that we (FI and I) did not invite her 2nd cousins to the wedding. We have invited 403 people so far....FOUR HUNDRED THREE!!!!! And we are paying for the wedding ourselves. My FI and I made the decision to not invite 2nd cousins of the PARENTS, especially since we didn't invite our OWN 2nd cousins! But the FPIL are very upset, and said they want us to send the invites, and IF someone accepts then THEY will pay for them. But I don't feel like we should invite MORE people...so far we have had 10 people 'decline' and we have 3 more weeks before the last day to RSVP.
What do I do? Do we invite them or not? Do I keep the 'peace' or should I stand by the decision we made?
