His behavior has gotten more exaggerated during the pandemic but he's always been like this to some degree. In many ways, he's great but he now won't tolerate any criticism. Our adult children know what he's like and he won't take any reasonable comments from them. I'm grateful that our daughter lives nearby and she understands how I feel. I think it is the beginning of dementia but he won't ask a doctor about it.
If he won't then there are ways for you to get help. Go to your doctor and talk about your stresses and wellbeing, adding that you think that this new behaviour from your husband is causing it. It won't be the first time that your GP will have heard this. Your surgery might also have dementia advice services or you could contact the alzheimers disease society for advice
