I have just started to read your post and I can see a lot of mind reading. You need more actions from him to really start to think that he is coming back. Like you I used to mind read everything that H did, but the fact is that he is still with OW. So don't look to hard for things, have no expectations and carry on leading your life like he isn't coming back.
Your H might be checking if you are still there waiting for him.
