Regarding coping advice for your husband. He should keep to his normal routine as much as possible. Since he works now, probably continue working through your hospitalization but take a couple hours of day of sick time for a visit. Spending time on self-care is important. Continue to indulge in hobbies, take long pleasant walks, exercise and eat healthy. Plan ahead for meals by getting friends or family to help bring over a meal or two and have easy to prepare food on hand.
I have no idea how another person would react. I do know that it is possible to manage.
The most important thing is for your husband to take good care of himself. Even if one spouse is ill, both are important, and both are worthy of care and attention. All too often, the well spouse's needs get overshadowed and forgotten in the face of the more obvious needs of the ill spouse.
