Wow this thread is really surprising. I really didn't know that this type of thing was so common, I'd say it makes me feel reassured that myself and OP aren't alone but it really doesn't.
A pp said about not knowing why people don't talk to their parents, the thing is, at least in my situation, when my dm died I was quite young (an adult, but not in the place where I knew or understood these things) so it's not a conversation I could have had prior to that.
My dad used to be very generous with money and very open, big birthday presents and Christmases. He'd treat his grandkids, take them out etc. Since his new partner though he he become very cloak and dagger, I get £10 in a card, a week after my birthday, in a card that has an incorrect age on. My brother hasn't had a card in three years. He hasn't spent Christmas with us in 7 years but they have a huge family and friends party on Christmas Eve, we're not invited. Her daughters spend every Christmas Day with them after the agreement was made they'd not spend it with either for "fairness".
My mum did a lot of this Christmas and birthday stuff, but even his relationship with money in general has become strange. His partner sold her house, has a second property, savings, sale of her mum's house, pensions from her first husband but claims poverty to him. He gives her £2k a month for "groceries" and he pays all their bills (information my dsis has managed to get to the detriment of their relationship) and for some reason her unemployed daughter has a very nice flat, an Instagram full of fancy dinners and nights out and her other struggling daughter has had three foreign holidays, a brand new German car and a £2k watch.
We would never tell him how to spend his money, and I'd much rather he was off gallivanting and seeing lots of women, but the relationship dynamic has changed so drastically that conversations that could have once easily been had are now impossible and lead to df having a strop for weeks afterwards.
I'd hate for our last conversation (as both of their health is deteriorating) to be one of anger and I end up holding my tongue in order to keep the peace and hold some sort of, at least vague, relationship with my dad.
This weekend I've just discovered that when he got rid of his storage unit (with all the furniture and effects of my parents life together), it seems tucked at the back (after a huge argument with him about allowing us access to pick out not only sentimental stuff but our own stuff!) was all the photo albums and framed photos.
I only have three photos of my mum now.
