What does 'honoured' mean in this context?

[Tomm98]

I spoke to someone who I knew from school about some worries I had. He got back to me saying something like: I'm honoured that you felt you could confide in me and I am glad that you did'

Why did he use the word 'honoured'? I'm still unsure what 'honour' I could have conferred on him just by confiding in him. What does 'honoured' mean in this context?

(I struggle mildly to interpret things like this correctly on my own at times!)

He means he appreciates your trust.

Or he's pissed.

In this context honoured indicates that he takes it as a compliment that you trust him and his judgement enough to talk about personal stuff.
