Hi Michelle,
I can relate to this. I do not share a good relationship with my dad as I watched him be abusive to my family and generally just not a good human being. But he did provide for us and raise us up. I am grateful for that part.
He is in good health but humbled by aging. Now he is the person in the vulnerable position and expects everyone to be fawning over him and have sympathy for him. But how you treat others, especially your own family comes back.
I struggle with not knowing how I should feel if something should happen to him. What if I don’t feel anything? It is a troubling dichotomy of emotions constantly!
Wishing you peace in this difficult time. Hang in there!
