Ten years ago I married a man 25 years older than me. I always knew I would care for him when he got older and that never bothered me. But now he has become the caregiver for his aging mother with parkinson's and beginnings of alzhiemers, which means that I am part of that care system too. His step-father never liked the fact that we were married and so for many years we were not in touch, I barely know his mom and she doesn't even realize that we've been together for 10 years. He has moved into her house an hour away from me, I visit on my days off from work.
I feel so selfish because all I can think of is me. I keep thinking that this is all I have to look forward to for the rest of my life. We will care for his mom until her passing and at some point later I'll have to care for him and probably my own mom and/or grandparents. I fear this is all I have left in life.
