-Your sentence seems to be hinting at gaining a greater degree of understanding about your feelings for your father. But the keyword here is resolved, which implies something (here specifically, your feelings) that formerly was seeking resolution. Why not be clearer by stating the following? :
I seem to have resolved a lot of former feelings of _____ about my father.Fill in the blank with what exactly what those former feelings were, and your sentence now has more clarity for your reader.
By the way, Mark Twain might find some sympathy about your growth in understanding:
When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much the old man had learned in seven years.
