Merry Christmas! 
Will try and keep it brief, getting married this year and generously both sets of parents have contributed an amount of money... Or so I thought. Luckily we had not actually factored the contributions into the budgeting as I've seen a few friends have this happen.
Turns out DPs parents have reviewed the amount and can no longer contribute due to some home improvements and a long haul holiday. All organised after we set a date 
My AIBU is this, I feel that we shouldn't accept the contribution from my (single) mother. I am sure she would love to go on a luxury holiday etc but has instead chosen to support us.
DP thinks I'm being ridiculous to turn it down and MiL thinks I'm being spiteful. I do understand that I am somewhat emotionally biased with this but I feel that it is vastly unfair that my mum who is by herself and retired is contributing vs my inlaws who both work and have decided to put personal want over their son.
Am I being daft?!
