How can I handle caregiving for a husband that has increasing demands?

Therapy? As we age, more and more demands are placed upon us...And how we cope with those demands is crucial to both ourselves and our spouses. You need to have some time for you! if this doesn't help the overall situation then a sit-down with your husband is in order; but(if it comes to it) sometimes a couples therapist can make a good mediator and help you both be aware of each other's needs.
