Rose,
I am.
Why would I want another woman?
I am perfectly fine living alone.
I got this from my father, he never gave up on my mother and they are still together after 42 years.
You will never give up on your children, right? No matter how much they make you suffer, they disrespect you, they cause you problems, they insult you...etc...So why would you give up on your spouse, it's just not an option.
