My step-mother died a little over four months ago. Recently, he asked how long she had been dead. After being told, he stated that every night he asks for her to come for him, but she has not come. Is this just part of the grief process or has he lost his will to live?
However, my father was widowed at 55 years old. He worked another 10 years full time and he was able after about 2 or 3 years to adjust to the loss of his wife of 22 years and they had dated for 8 years so he had known her for 30 years or most of his adult life. He had 0 interest in dating or remarrying, so his retirement was that of a widower, but he lived another 38 years as a widower. He was able to enjoy his life as a single man again. It depends on the person.
However, 4 months is not long enough for most people to regroup after a death. My father was not himself again until about 3 years after my mother (his wife) passed.
I'm sorry that you are going through this pain. You can certainly do everything you can to comfort and support your dad. It's possible that he'll work it through and move forward to a degree. It's likely even a doctor couldn't give you a sure answer.
Sadly, I do believe that your suspicions could be correct. It's not at all unusual for elderly spouses to die quite close together - sometimes within days. My mom lasted 5 months after my dad. She was done living when he died and we knew it. It just took her body some time to follow her heart.
However this turns out, you'll feel better knowing that you were there for your dad during his grief, ready to help in any way. If he's giving up, then that's his decision. there isn't likely anything you can do but love him.
Take care of yourself, too. It's a rough time for you all around.

When an elderly person loses their spouse it's not uncommon to feel lost and left behind. And four months is so recent, the grief your dad is feeling must be very profound.
I don't know how bad his dementia is but feel free to ask him how he's feeling regarding the loss of his wife. You're not going to put any ideas into his head that weren't there already and he might welcome someone inquiring as to how he's feeling.
Grief process or loss of will to live? Probably a little of both.
