For Better or For Worse.....
How far does it go? Some people take that vow to mean no matter what, forgiving all manner of transgressions and trouble. Others sign those divorce papers at the slightest provocation.
Sandra Day O'Connor resigned from the Supreme Court to spend more time with her husband, who had developed Alzheimer's. He now lives in a care facility and is in love with another patient there, having no idea who his wife is when he sees her. She isn't bitter at all. Likes to see him happy. Now, that's commitment, IMO. Could you do that?
