Seems like you are moving in the right directions in so many ways, but I have to agree with you, you need to stop the "I love you". As Sandis rules lay out, and you know, it just puts pressure on her to respond like that. I would let her lead on that. She knows where you stand, and will probably just feel forced and pressured.
Great job on calling timeout and walking away for a few minutes. Smart, allows you to collect yourself and allows for you to avoid saying anything damaging or reacting in a way the WAW wife is looking for.
Keep up the good work. Progress will be slow. Don't pressure or force, allow her to see the new you with your changes, and remember, you will be ok either way. Once you have that realization, not that I'm there yet, but I think it helps make you stronger, as you have security that you will be ok no matter what.
Keep up the good battle. Like hearing your updates.
