i was thinking about emotions too, lately,
my grandmother has died as well last week, but since she was living as a plant for the last 3 or 4 years, my grandfather sitting next to her, it was better for her to go.
emotions,
if i can consider myself an aspie...
i see emotions like something 'factual', i think nt's have some kind of conventions, but as these conventions are different for all nt's, it's hard to understand what they really are.
so i tend to stick to facts , if my husband says he loves me , what does 'love' mean ...?
that he wants to stay with me, living together, or that he feels like making love , or that he doesn't want any other man to touch me, or that he wants to have fun together, etc... ?
and for grieve it's the same, i'll translate 'being sad' into 'regretting it is not there anymore', since your grandmother prefered to die herself you don't regret it she died, so you don't feel any grieve, but you probably would feel grieve if someone you really felt like spending more time with would die.
