Sorry to gear that
@Bugs, try to stay strong. If it's any help, my OH had a bad stroke 10 years ago (but it was a bleed) He also lost the use of his left arm and leg, his speech and part vision.
He had to have the blood drained with a 4 in 1 chance he wouldn't make it. The surgeon said he could have ended as a cabbage if he did survive so it was a hard decision to go ahead with the operation. When he was discharged he was bed ridden and it was hard work but 6-9 months later he proved the hospital wrong and was walking without even a stick. He never regained the use of his left arm and walking wasn't great but he even manages stairs now. So don't give up just yet. Try and stay positive. It really does help you both. Life obviously changes, we can't walk costal paths etc. which we enjoyed but at least we could still have a life. Unfortunately we now have dementia and that's a lot more challenging for me.
