So glad to hear from you again, was worried you might be up for charges on murder!
I agree with Ellie on the QT stuff....yet, if H is in MLC, then I think that you are deep in the background there. So, just do your thing, only if you want to....don't force anything now. Also, your H just seems to me resting comfortably in limbo, of being wanted by 2 women and rejected by none. He is couching his low self-worth in this. I think you pulling back, gradually, sets your boundaries (that you will not be a loving W while he "makes up his mind"), draws the safety net from H and perhaps out of the tunnel to shed light on reality, and also keeps you sane. It lets him know the consequences of his actions. Also, I think alone time for the MLCer is good....let's them stew in their life, think and reflect....you're not always occupying his mind, letting him sit in limbo/denial.
On that note, can you at least get away for a few days here and there, maybe with your D? Weekends? So what if it's time with Monster, or whatever. That ride needs to go full throttle before it blows up for good.
Glad you're focused on goals again, and pulling back...WAAAAY back.
