Thank you for sharing your story. I can see how this situation is causing you to really look hard at your own actions, and how they contributed to the separation. I admire your ability to empathize with your H, and refusal to blame him, while still acknowledging the issues he is grappling with.
I am going through a similar situation, although my (now) exW has been gone longer. I find myself with almost eerily similar thoughts to yours and other LBS on these forums. I guess the encouraging part of that is, if our and the WAS feelings and thoughts are so predictable, perhaps the process of reconnecting via PMA and GAL, etc. really applies to your (and my) situation, and will gradually lead to positive change.
Hang in there. I'm rooting for you.
