Early on I had issues with my FMIL and the guest list....We gave her x amount of people and she went about 15-20 people over that. I asked her to cut the list and she would and then ended up adding more and kept saying that atleast 15 of her 101 people wouldn't come. I tried to explain to her that you can't depend on people not coming but she said she new that 15-20 wouldn't show.Well here we are 6 weeks before and the RSVP's are rolling in and she only has 2 no's with and only 16 more response out and we already know 12 of those response will be yes (family members) That leaves her with only 6-8 no's at most.....Do I suck it up and pay for her extra 10 or so people or have FI confront her on it and tell her she has to pay?I have brought up my concern to her countless times and all she says is not to worry about it and we can borrow the extra from her, meaning she wants us to pay her back even though they are her guest....she did give just as much $ as my mom but she has 20 more people and we have also put it ALOT more then we wanted, even though we did this big wedding for her.PLEASE GIVE ME ADVICE, do we let it go and pay the extra $1500 ourselves or make her pay for them
