Does NC ever feel petulant to you?

Hello,

I know NC (or in my case very limited contact) is necessary, but does it ever feel childish or petulant to you?

Today I saw XN for about ten minutes at our workplace. He was seated right in front of me. I had some work info to tell him. I emailed it to him, then left without speaking to him.

I left feeling like a big sook. But at the same time, knowing it is the best course of action.

Does anyone else experience this kind if CD, and how do you deal with it?

Thank you.
