I've been following your sitch - mostly because I try to read ALL the advice that gets put out there.
I want to offer lots of hugs!!! I think you are holding up your head beautifully during this stressful time.
I'm no expert but from everything I read - waffling is normal. The other is that we tend to walk away too soon and not to lose hope. But, maybe I'm just gleaning things that make me feel better?
I think you have shown immense strength while still at times being compassionate to your H. Keep up your boundaries. I think you can both be pleasant and show that you are over it. You are standing for yourself. You will not stop for breadcrumbs. From what I've read of your situation... it was when you created your boundaries that H was pulled toward you again. Take a step back and work on that a little more. He is still peeking in your windows out of curiosity...
