It sounds to me like H is having days where he knows that he wants you (the upbeat behavior, doing things like he used to) and then days when he thinks he wants her. Believe me, I saw that alot with my H. There were days that were right, then the next day be completely off and I did nothing to provoke it. Keep doing what you are doing, you are doing fine. It is hard, I know, believe me...But you are doing ok.
Take the days that H is acting like the old loveable H and run with it...Maybe you can stretch those moments out to days, even weeks, and then maybe he will see life is great with you and the family you have built.
But lets start with making it last more than a day. lets not bite off more than we can chew...LOL
