I might go...

I let him know that I may go.
It's not that I'm unhappy or unsettled... there just might be an opening someplace else that will suit me better.

He was a class act.
Knowing that I thrive for personal challenges and evolution, he made it clear that I have all his support. I also made it clear that I won't budge without letting him know in advance.

I wish everything was this transparent.
