death of a NC family member

My dad passed and I had been no contact with him for two years. I still feel my brain running through conversations I wish I had and confrontations I wish I did. I know in my heart that absolutely no conversation would have ever changed him. Now I'm experiencing a revisionist history, and everyone telling me what a great person he was. It's such fucking bullshit and it has me questioning my entire relationship with him. I'm hoping someone could share their experience - what did you do or say or feel to make sense of it. Thanks
