A few things that you can try, for now, which you will read more about in the books when they arrive.
There is GAL, which of course stand for "Get A Life". What that means is to find some things to occupy yourself during any down time and that will keep your mind and/or body busy.
Of course, considering the issues the two of you have had regarding previous affairs, you will want to be sure that the activities that you do which might be with others, is open and transparent. Sometimes we will talk about being mysterious. In your case, mysterious could lead to more strain on trust.
What can you think of that you might do to GAL?
Also, 180s. If you know your W has a valid complaint, or if there is definitely something that you think you could work on, personally such as helping out with housework if you had not before, or being more involved with the kids in mundane tasks or extra curricular stuff, or something regarding your health, learning better listening and validating skills with anyone, even if not your W, that would probably be a great idea. These are "growth" things, but also related to things that you really were not doing (much of) in the past, but will do now.
