Deciding to better your life shouldn't need to be a secret. You know I've paid close attention to your journey here so far and you are most definitely on the right track.
This situation is obviously bothering you, so I'd go ahead and say something. But here's the deal--you need to have no expectations of what she's going to say or do back. Don't just manage your expectations--let them go as best you can.
You have no idea or control over how she's going to react. She may be enthusiastic and be wholeheartedly on your side. She may think or even say she's seen it before. She may be thinking that you're just doing now what you should have been doing for years. Her reaction is completely out of your control. Put the news out there and then just let it go and keep doing what you've been doing for the last 44 days.
You're doing great, Fradley. Keep on keeping on!
