Jesus christ 🤦🏻♀️ it never fails to shock me the lengths some parents will go to just to exert their 'dominance'. They never seem to care when the other household is unwell/ will have to change their plans/ have got sick of their shit but it's the end of the world and you're the worst person on earth if you can't bend over backwards for them.
I've told DP we do no more favours for ExW, simply because everything is on her terms and she never even tries to help us on the rare occasions we have asked (and they are rare, maybe twice off the top of my head in several years)! She booked a holiday, over the only 2 days she has DSC that week, and then kicked off at DP because he genuinely couldn't accommodate us having them 10 days on the bounce. Said we were trying to ruin her life 🤣 she could have taken the kids the following week, but that's obviously too much to ask!!
Her birthday is sacred and can't have the kids, same with mothers day, valentines day, Christmas day, new years eve, new years day, bank holidays and her partners birthday. But fathers day is a demand DP has the DSC (even if it falls on her day, although DP loves having them that day) and sod DP and I if we want a special day to ourselves.
It would have to be a whole series of books, but would definitely be a best seller!!
OP we have railroaded your thread (sorry!!) but if anything, learn from this conversation. Put your foot down now and offer your set of bollocks to your DH if he's struggling to locate his to parent his child, be the man with responsibilities he's meant to be and look after his own child, and to stand up to his Ex and tell her to also face her responsibilities as a mother. Trust me, you say yes once and you suddenly become the unpaid help who is never even considered as a whole human being with their own life!!
