Gonna echo using “caregiver.” It’s commonly used in questionnaires for social health.

Now as a divorced 34 year old with no caregiver, you have no idea how much help it would be to have another pair of hands around the house lol.

The comments that are giving flak- the situation you’re describing isn’t terribly uncommon historically or internationally. Even in cultures where divorce isn’t possible, men still get widowed.

It’s just not described the way you did.
