He feels I should know his every need. I don't. He has spent the last 6 months in a nursing/rehab facility. He came home a week ago and feels I'm not giving him the care he needs. I don't know what he needs. He went in using a walker and came out in a power chair. Would going to a CNA class help? I'm lost in the sauce.
He has spent the past 6 months with trained personnel who did know what to do and how to do it. I suggest you hire a home health aide or someone who can show you the ropes and ease you into this caregiving role. I have taken the CNA class and actually did pass the state exam at the time, but I've never worked at it and it expired. However I did learn a lot of the basics of care, how to move dead weight by yourself was a big help. At that time, it was offered at the local community college and lasted less than a month. We did do a lab in a local nursing home. It was very intensive and lots of studying at night. If you have the ability to take the class, I would recommend it. A lot of nursing homes will also offer it, but they require you to work there afterward.
Good luck and I hope that your husband calms down a little as he gets used to being at home.
On the other side of the coin, could be hubby is upset with himself that he now has to use wheelchair now, so he is taking it out on the closest person which would be you. Is it fair, of course, not. Is he assuming you will help him with things that he should be doing for himself?
You might want to prioritize the care aspects you're providing him and learn more about those first; taking over someone's full time care is a big job if you're not used to it.
