My Wife Walked Out

[RSG]

Little update: It's been a week today since she left. She's at her parent's this weekend, and I have our son. She's constantly critiquing me about what he eats, when, naps, etc. When we talk/text, we only discuss our son and what's going on with her. I haven't initiated anything, and she doesn't ask about me.

Question: When she says something like "I'm going on the boat" should I be saying something like "have fun" or give a more non-descript response?

I'm working hard on detaching, GAL and being a lighthouse.
