Now I'm home after 5 days away working, not sure what to do.

My W has requested I do something about our 4 year old, I believe he feels the stress and my W can't deal with this guilt or him now.

Talk openly about trip and what I did when she asks or give polite short answers.

I'm happy playing with the children and laughing.... X

I haven't asked her, just some small chat about swimming.

Any advice?
