It's very common as men age.
To be fair they have to cope with us and peri menopause as we age, so a bit of give and take is wise.
Habits of thinking and behaving can get very solidified and be hard to shift.
But those habits and behaviour have an effect on others and you have the right to speak out if they're distressing you.
I'd be inclined to write it all down, get clear, then have a formal conversation with him. Present it as something you're worried and upset by. It may be caused by a health issue. The mood swings may be caused by anxiety, fear over finance, work, etc.
Be prepared for angry, defensive reactions, so choose words with care.
Maybe a complete look at your lifestyles together? Diet, exercise, drink, sunlight, good sleep, addressing financial and health worries, etc.
Or if may be this is the real him, coming out. Do you want this to go on? It does get worse.
