I have driven automatics for years & love them, I have problems with my left ankle so they are ideal, I can however drive a manual if I have to, you never forget. Confidence is a big thing, plan journeys, get a SatNav I hated them & I can map read .
I had to drive to DM's a few years ago, first time I had made the 300 mile journey on my own, mostly Motorway driving which I hate. I stopped half way for an overnigtht stay, I now do the journey in one with about 3 stops.
Find a good driving school & get back on he road before your DH has to give up driving. My DM was still driving in her 80s only giving up due to failing eyesight. My DH would drive all the time if I had let him but I used to take the keys off him & we often shared long journeys, I have been widowed 6 years so I'm glad I kept up my driving skills despite DVLA keeping me on an Annual Licence I live on the edge of a small Town & at 63 have over 2 years to get my Bus Pass. Taxis are expensive round here especially into larger Towns.
