John Adams

They would never become accustomed to being separated. "I can do nothing without you," he was to tell her one way or another, time and again, and always from the heart. She would have him no other way than he was; she believed fervently in what he was doing, encouraged him in the role, and wished no other for him; she wanted him to be where he was doing his utmost for the country. And still she desperately wanted him with her. Each worried incessantly about the other's health and well-being, at times to the point of making themselves ill.
