@Sammyiam - work through it here on the forum and no, it doesn't sound dumb to me. I was able to have a relationship with my father in spite of most of the difficulties you bring up in your post about to the end of his life. It was hard, but I am not sorry I did it. Somehow to me, doing the harder thing at the end of his life made the regrets less. Your uncle's (?) opinion, for instance - bringing up pivotal moments in his relationship with her many years ago was likely ill timed considering the circumstances... but he most likely was trying to convey a decision he made for himself.
For what it's worth, my brother was my father's preferred sibling. My father was my first and longest term abuser. But, in the end... like you shared Sammy, my father was the only one I'd ever have... and I chose to honor the relationship, even if I couldn't recue the relationship with the man. Though he may have wanted to hug me (there were some awkward moments)... I couldn't allow it. But I could call him and check on him every day, I could and did assist him with allowing my brother to go to be with him before he died. I actually had a trip scheduled, and prepaid air fare and a hotel and a rental car... but as the travel date neared, he told me "I don't think I can make it til you're visit". And I told him, "Dad, I'll be okay." He died very shortly afterward.
It was a 9th hour very small thing. But by doing the more difficult thing, listening to my inner voice that told me to stick and go through the experience with my father... well, I never got his hug or full reconciliation but I did get to do my version of "right" because he is/was my father... and I got to hear myself tell him "Dad, I'll be okay".
As far as wanting your mom to hug you, keep you safe "so you don't have to face the world"... well shifting out of child mind and into adult mind if you can do so is more beneficial but of course as you deal not just with the relationship, the seriousness of your mom's health issues... but also the "death" of a fantasy that stemmed from a very real unmet want/need/desire... well, you got us to help you work through it or listen Sammy, 'k?
