Will try to make long story short.
My brother (intelligent, earns good wage, responsible job) still lives with my parents (in their late 70's) - he has never moved out of the family home (normal 3 bed semi. My parents admit they have made him too comfortable. When they go on hols they cook and freeze enough meals for him to just defrost and do rice with so he does not have to cook as he would be tired after work.
I moved out early 20's when got married - lasted 8 years - moved back for 3 months when split up then got my own place and remarried. DH works hard and we own our own place (with a mortgage) and I would say we are reasonably well off.
I have always been the one who helps with family events / organising - my brother does nothing. Example - my mother wanted a surprise lunch for my father on a big birthday a couple of years ago - asked to do it at our house - said she'd invite about 14 people. It ended up a sit down 3 course meal for 30 odd people - with me cooking and DH and I turning house upside down. I asked brother to sort out the wine - he did not - as he said he did not drink it and did not know what was good. Gave us a cheque for a third of the cost of food. Lots of other examples I won't bore you with.
I hosted Christmas (again) this year - I normally enjoy it but this year my brother turned up with nothing (well, normal prezzies but not even a box of chocs or a bottle of wine to say thanks for the meal) - my parents were planning on staying a few days. Brother instigates conversation over Christmas dinner about wills and what will happen to the parental house. Turns out that M&D plan to sell house when 1 of them dies, move into a 2 bed flat with brother, then when they die, leave flat completely to brother (so he does not have to get a mortgage as that would be an unfair burden) and if there is anything left after paying care or nursing home fees it will be split between my brother and I but mostly to my brother. My paremts got upset talking about it and somehow this became my fault - and they left boxing day morning and although I've rung them 3 times since they are being very cold to me.
So - I know that it is my parents money and they have to do what they feel is right - but I feel that they are pushing me out of the family (as I moved out the impact of one of them dying will not be so great apparently!!) - to be fair my brother thinks this is unfair as well.
I am very confused and hurt - I have tried so hard to be a good daughter. It does not help that my mother is loosing the plot a bit and I can no longer talk to her about things like I used to as she has started to embarass me in front of friends and business contacts by repeating things that are personal in public. My Dad is deaf and so does not hear them and then refuses to believe she would say the things she does.
