So backstory. Partner and I have been together 5 years. He has 2 biological kids from ex wife (boy 12 & girl 13) she also has a son (boy 16) when they met, my partner has took him on also. We have the kids every Thursday for tea and every other weekend, extra in hols. partner pays csa for 2 biological kids every month and we buy majority of large presents for all three ie phones/macbooks.
We have a 1 year old son now together and relations between all are pretty good, I have never take a step mum role really but we get on well and there are no issues. We didnt gonon holiday last year as I was pregnant however the year before we all went to Wales for 5 days and it was great. Now... my family are not close with the other kids as they rarely see them and they have lots of their own family that needs to fit time in with. My dad has just announced he wants a villa away for his 70th in August, about 8 members going plus my my partner and son, they are treating is to paying half as we are just about to buy a house so were not planning on a holiday.
Bottom line is we simply cannot afford 3 flights in the summer holidays and it's a event for my family not my partners which would be different. I refuse to miss out on this but partner is getting a bit of stick from ex wife and his mother about this. So he may decide not to come but then will he missing our sons first holiday. I just need opinions as I starting to become resentful for the first time ever...
