I think your financial situation is exactly why there are "millionaire next door" types, that people don't know about. In our current situation we are doing very well, have a good stache and are on our way to FI, but probably won't RE unless we don't enjoy our jobs anymore. My parents are retired (Dad still works 8 hours/week at a cushy job to keep him busy - as he gets in trouble when he has no obligations), house paid off, they have a decent stache (not as big as ours) but have a pension that covers the both of them. So they are not spending their retirement and pension and SS covers their lifestyle, so their savings should just go up. We talk openly about money and this has helped me get educated on the subject and see the light early, help educate my parents better (probably saved them $100k over the last 7 years in needless fees from old retirement accounts) as well as my sisters. Between my side of the family, we all know what we're worth, talk openly about money, problems and solutions, I essentially help manage my Mom's accounts b/c my Dad can be impulsive, but whatever, they have enough that it really shouldn't matter much.
DW on the other hand has her Family, 1 brother who is actually FIRE, but frugal to the extreme where it hurts their families relationship. Other brother who spends everything and probably not well off financially, just everything on credit, living the typical American lifestyle, then my Mother in Law who will answer direction questions like "how is your retirement account doing" with "Fine", or "My retirement plan is to walk off into the woods" or whatever. I've offered help but I think she believes this is a sign of weakness and doesn't follow up, so I leave it alone.
Long story short, I have a much better relationship w/my family b/c we can talk openly, and I'm not worried about my parents or sisters financially. It takes a huge weight off of my shoulders, and nobody wants to watch their family struggle as they age, especially when they are in need. DW's Father recently passed and everything was about the cost of care and things like that and it took a big strain on the family.
My point is that if your parents are expecting things of you then you may eventually grow to resent them b/c of it. The writing is on the wall that my Mother in Law will need help one day financially, and I am not happy about that b/c she retired before she should have, she doesn't save or plan, she lives paycheck to paycheck off of her pension, she is a closed book regarding her finances and I see the writing on the wall that it's going to come back to bite her.
IMO, I would try to educate your parents about saving, retirement, spending w/in their needs, etc. I would also not talk to your family about your salary, savings, net worth, etc. as they will hold it against you like "my rich daughter", when they seem to not know much about finances if they are reliant on you. If you have extra and want to spend on them then that's fine, I see others message about taking their family on vacations, and that's awesome if you enjoy them and they don't expect it as a hand out, but if you are obligated to pay for their lifestyle then I know it would make me bitter. We used to help out my brother in law early when he was young as he had a child and not much money, so we all chipped in a bit, then he bought a huge TV for a lot of money and a nicer couch than mine and on credit, and at that point we stopped making those payments b/c he was just spending whatever money came in.
I would continue to try to educate your parents, analyze their financial situation, ask "how are you going to pay for that", don't put their retirement strategy in the dark. Maybe they will need to move to FL or someplace specific for older people on a fixed income, maybe they move in w/you one day if you enjoy their company. But I imagine nothing makes a relationship worse than having someone financially dependent on you and you don't want that to be the case.
My relationship w/my family is so much better b/c I don't have to worry about them, both my sisters and parents, and I know when they age it will be tough, but certainly much easier since they have their financial act together.
