I think the question has to be, if someone is being untruthful and you want to confront them, you have to ask yourself why it is so important to you.
If it matters and has value, then confront away. I say you should have the balls to ask the questions that need to be asked.
Honesty is a tough one because unfortunately I believe a lot of people sometimes view things differently and what seems honest to one person, may seem dishonest to another. We all factor what is honest based on what we know and believe for ourselves. We all have the ability to make assumptions and that can lead to us questioning the honesty of others. Its a catch 22 sometimes.
The important thing is that we are honest with ourselves, and the people that matter to us.
