So long story short, my fiance's parents are paying for the reception food and open bar (since they're the ones who wanted it) and for the church. Other than that all of our wedding expenses are being paid by us except for the small amount that my parents are able to help with. I don't want to sound like I don't appreciate their help, but my future MIL is wanting control over way more than they're paying for. Invitations and cake are the biggest things. She keeps insisting that we should save money by getting cakes from Costco and that cupcakes (which is what I want) would be a bad idea. I'm getting really aggravated because I want her to be involved, but I feel like since I'm paying for those things she shouldn't get a say in the matter? The biggest issue is that her guest list of her large family (not including friends) is quickly approaching 300!!!! She thinks only half will show up...but she wants to know how many of my 100 friends and family I believe will show up so she can attempt to only cut a few of her family. Our reception site only holds 250 (not comfortably either) and I'm worried that if she invites 300+ and I invite my 100 that we will end up with WAY too many people saying they're coming. With them paying for the reception food, do I have to give up some of my invitations to try to accomodate the possibility that most of his family shows up? I'm rather upset because we were thinking we'd have maybe 175 guests at most and now I'm seeing my costs for cake, centerpieces, invitations, etc increasing. PLEASE HELP!!!
