To move away from elderly parents?

Oh I'm having these thoughts too. I'm younger than you but my mum had me when she was older so she is 70 something now and I'm 35+. My partner really wants to move to a different area we ended up living near my parents by accident as I got a job in the area and we relocated. But the thought of moving back across the other side of the country away from them now fulls me with anxiety ! My dad had a heart issues recently and I drove him to hospital and stayed with him in a&e as my mum just panics in these situations, it's the first time I've had to step up like that. I'm an only child.
My partner is desperate to move in the next 3 years but I worry incase they expect me hang around! But on the other hand if we stay in this area we are just waiting for them to die so we can move! And that doesn't feel healthy either.

Depends on what you see happening in the future? Do you envisage your parents in a care home, either where they live now or where you move to? Or do you see them insisting in staying in their own home perhaps with carer support? Do you have the kind of relationship where you would want to support them practically or not? I'm assuming not...

Do they have power of attorney established?

I moved a long way from my parents,k and as they entered their mid 80s, they ended up moving to be near me. One is being removed from a care home to live with me right now. They were fine in the home, until they declined and needed more support. I nursed my mil through end of life in her home.

Is there any compromise? Or do you even want to compromise?

If you don't do it now you'll not get the chance. Ask them what their plans are for when they need care .

Do it. We didn’t as FiL used emotional blackmail to keep dh close. Despite dh doing so so much, I’m convinced FiL would have had a better quality of life and 24hr care in a home.
Our life was crap, FiL had a crap life and now dh feels too old to cope with our retirement dream of moving to the coast.
Honestly I could weep but that would accomplish nothing.

No, just make sure that they have a future plan as to what they are going to do when they need extra help. I currently live 3 hours away from my parents, DH parents have both died. Within the last year, my mum has developed advanced dementia and is now in a care home unable to recall who I am and my dad's health needs have increased to a level he's likely to need residential care in the next few months.
I have a lot of siblings and we've each decided how much we are prepared to do or not do, that's an entirely personal decision.
