This is the part where you step back and work on you. YOU need to find out what YOU want to be. What makes YOU happy. Be that fine confident person you know you are. GAL helps a lot. Do things that you want to do or have wanted to do. This way you can have your identity again. When you work on you in a positive way (for you not your R or him) he'll notice.
One of my focuses during my ride is to be a better dad and to make my time count when I am with my kids. I have been very consistent with my behavior because I am doing it for me. My W noticed and couldn't stop praising me about my fathering skills. If you do good for you people will notice, but more importantly you will and you won't have to worry about what other people (H) thinks. But thats just my two cents.
