High expectations, be aware

Don't feel I did my job well, couldn't focus. When I text T to tell her I wasn't feeling good today and she replied asking whats wrong, I realized I was disappointed. I'm disappointed with a person I highly respect and loved, my uncle. A man who is supposed to be a priest, one who lives according to God's word, but it doesn't show.
How he behaves in my family crisis is very selfish. He only thinks about himself. When I saw him yesterday, he wasn't saying any wise words, instead he continually was telling me stories in the past of how he was hurt by words. Words of his sister, my aunt, and other people. He was seeking understanding, to know how he felt when he heard hurtful words about his past, when he was young. How people seemed amazed he is more successful now, like they were hoping he wound succumb in poverty.
In my opinion, we can never change the past, and we can not change the way people think. But if we were like a failure in past and successful now, shouldn't we rejoice in that. It depends on one's perspective.
But my supposed to be follower of God chose to be a victim as a perspective and he demands others to know how he feels.
Very disappointing. But I guess, this is what you can get from having too high expectations from a fellow human.
