I also wanted to add that you are the only one who can control expectations. And the more you wish for something that you have no control over, the greater your frustration will become. And really that is a HUGE obstacle to detachment.
Keep in mind no matter what the status is of your marriage the one thing you and your H will *always* be is co-parents. At this stage I would look at any family activity as a co-parenting experience and not link it to your marriage in any way.
The more time you spend looking for clues or signals or signs from your H the less time you spend working on you. But if you are going to work on you make sure it's for YOU and not for your H. When you are detached it won't matter to you if your H notices your changes or not because they are all for YOUR betterment. It may help the R with your H for a marriage or it might make you a stronger co-parent but essentially they must be for you and the betterment of your life.
