Any suggestions for a loved one who can't use a computer?

Me again . . . . Haaaaaa. You folks may really tire of all my wordy posts over time.

But, I have a need for some suggestions in how to handle having to do all my husband's technical communications for him. He can barely handle scrolling past things on his smart phone, let alone communicating with doctors, etc. He can't type (huge issue), which leaves me to send and respond to things FOR him. I've tried to show him things but every time we sit down at the computer, he's just all thumbs and can't figure out how to get himself out of an issue if something goes wrong. Can't seem to grasp the functions of the mouse or how to use a keyboard. And, God forbid, if something doesn't look the same on the screen as the last time (i.e., updates, etc.), he gets completely befuddled and frustrated.

Any suggestions? Cuz, it would make my whole life a lot easier if I didn't have to relay messages, look results up . . . . stuff like that. When I do, obviously, I get sucked into everything. Going back to playing phone tag with folks is problematic as well, since he seldom keeps his phone nearby and the delay involved with that is obvious. Plus, if we have two phone numbers out there, I'm usually left with trying to respond to people on two different phones if they need an answer and he's unable to talk to them when they call back, which has been the case if he's in an MRI or CT scanner or sedated or something.

I don't know if there is a solution to the situation but if anyone has any suggestions, insight or similar experiences they would care to offer . . . I'm all ears.

As you may have figured out by now, after all my wordy posts, we are a unique couple with unique problems. Soooooo, "special", aren't we?
