DH & moved from Surrey to Somerset as we needed to downsize & wanted somewhere half way between my DD & DH's DD, his S had moved away & we were never close. Luckily we sold our house & found our new home easily but DH did find it stressful. Just short of 12 months after our move DH was diagnosed with terminal cancer. I was a widow 15 months after our move, I was only 57, not working as I was DH's carer, still able to drive.
One year on I made the decision to move closer to DD (with her agreement). Took over a year to sell my property then a cash buyer came along, 3 weeks to get organised so I had nowhere to actually move to. However I had looked at various properties in a 10 mile radius from DD. So it was put furniture etc in storage, 2 weeks with DD & then I rented a holiday flat for a few weeks.
I was lucky enough to view a Mobile Home (we had one in Somerset) on my 2nd day in Devon which I loved. Few complications before I could move in but it happened.
I live in a small Town with nice shops, Doctor's Surgery, Library, several Pubs & Cafes, decent bus service & Train Station in nearby Town which is where I do my main shopping. GP Surgery has a volunteer driver service who (for a donation) will provide transport for Doctor/Dentist/Hospital appointments. I am about 10 miles from my DD, her OH & 2DGSs, I don't see lots of them as they have busy lives but it is easier for me to visit or them to visit me. I am close enough but not too close, I have made lots of friends, have lovely neighbours & at the moment despite health issues very independent. It's the best move I could have made. I am not required for childcare as DD had built a network of friends before I moved but DD is near enough if I should require more care as I age.
Meanwhile my DM still lives in Yorkshire, she's 90 & still independent but it's a 300 mile journey, I have to drive to see her as she lives in a small village with no ammeneties, luckily she has good friends who take her shopping, to WI etc but DD & I worry about her future.
