I've had the weird dreams, too. Disturbing dreams where my H is there but not there. Subconscious sh!t. Kept me awake for nights for a couple of weeks.
For what it's worth, I think you & S are doing great. And the better you do, the more H sees, well, if he decides to come back, you might not be so eager for that life anymore. Who knows? It's a bizarre conundrum.
At this point, I haven't lost ALL my love for H, but I've lost a ton and a half of respect. Time and distance gives you the ability to see them in a different light.
Do I sound like a downer? I don't mean to. I only mean to tell you I think you are doing absolutely fabulous, and are finding strength in yourself you didn't know you had.
