Companion Care Needed

About who needs care: Has dementia, is fairly self sufficient (showers, uses restroom) but he does need help with meals. Really just looking for someone who can watch him because we're not comfortable leaving him alone. Honestly, he's really not motivated to do much. His wife of 43 years just passed so he's grieving, depressed and not really motivated to do much. Fun, right? About the care needs: Someone low key, not high energy, not too talkative, is okay to pass time helping out and will probably have time to do there own thing. Services needed include: meal preparation, errands / shopping, light housekeeping, and companionship.
