FMIL crossed the line!!! What would u do?

Several weeks ago she asked how many people we were looking at for the rehearsal dinner. I said 20 (that includes both sets of parents, the BP, one set of grandparents, my hair/makeup person & her husband--they are like family to me, and my mom's best friend for Cali who is also like family and flying in a week early to help out). She called today to tell me that since they are paying for it, they arent inviting the last two couples I mentionned because they arent family or in the BP. I explained that I wanted them there and wouldnt feel right if they werent. She went on to say that its adding up to more than they wanted to spend and the place is kind of expensive, so they just wont be inviting them. I replied by saying 'well...they have to be there. I would suggest then that you look at cheaper restaurants.' WELL -- she comes back with: Ed and I are paying for it -- sorry, they arent being invited.' I said-- 'I will be talking to chris (my FH)about this then...we need to discuss it first' So she says...heres the killer-- 'No....I will be talking to Chris and find out what HE wants' Ummmm excuse me! Does she think he will go against my wishes???? And my parents (who were in a much worst financial situation) paid for the e-party which was 70 people -- most of them were HER family, not mine!

I just cannot fathom not having these 2 couples there -- they mean so much to me and are travelling far to be with us. i cant imagine telling them 'no, you have to eat on your own'. Thats horrible. I'm almost contemplating telling her 'thanks for the offer, I'll pay for and plan it myself'. What a b**tch!

What would u do??

Oh--forgot to mention-- she claims she asked around and she was told that no one but the BP and immediate family should be attending and that only people who directly helped plan the wedding should be there. Well, in that case NONE of them should be there! The groomsmen and bridesmaid didnt help plan at all and neither did the fathers!
