You've started this as a 180. Dolphin is right, keep doing these things with no expectations. Your W may not say anything about it. She does notice though, and she may be just waiting to see if these changes are permanent. Keep them up no matter what is said or isn't. It's the only way to prove they're real and lasting.
It's important to maintain them even if your W keeps threatening to leave.
You feel better mentally and physically because you're being proactive instead of reactive.
