We have saved to take the dc to Florida this year dd17, ds16, ds7, dd5, ds3 and dss16 dd15.
I am a stay at home mum because of dd5 and ds3. This means dh is paying for the whole holiday. Dh ex has agreed to the holiday (its 4 weeks so most of summer break.) We asked her to pay half the cost for her dc as last year dh paid the whole cost of the holiday for her to go away with them. This was told to her when dh gave her the money for the holiday. It works out less then the cost of the holiday and she has had a year to save. She is now refusing to pay dh and has said that I should pay half and that I am not contributing to the cost of the holiday.
I must make a note dh and ex take in turns to take dc away every year so dh one year, ex the next.
Aibu to think she should mind her own business about finances and me.
