W let me know she’s not doing well. I asked if she wanted to talk about it.

This is DBing 101.

Why on earth did you ask her to interact? She then says no and you feel crap. Again.

EVERY TIME YOU INTERACT YOU LOSE.

Try this:
Crazy ex: “I’m not doing well.”
Rockon: “That sounds tough. I’m leaving to get ready for dancing.” And leave.

The answer is staring you right in the face - Talking always makes you feel worse.

Also, I think you’re still getting validation wrong. Replace “validation” with “repeat what she said back to her and then immediately leave”.
