He helped the homeless, addicts and the scared

My many sins in marriage were disclosed
He taught me Chess,I won, he was  annoyed
Yet did not tell me till his dying days
He must have sulked to cover his dismay
All at once he  poured out my mistakes
I was too brilliant for a  man unwise
Who married me because I had blue eyes 
I knew the villain when we watched TV
Now I see the true villain was me.
Yet he seemed  most  learned as he spoke
His weighed his words that helped so many folk
While I struggled teaching maths, it’s hard
He helped the homeless, addicts and the scared
Then I cooked his dinner, fed the cat
Fit for nothing much,I   darned my hat
Now all that I assumed for forty years
Hid his anger when I thought he cared
Was our love a play within a play
I held  his dearest hands, he passed away
