The fact that these things that you have had to confront in this time were so unthinkable up until a few months ago is a sign of what type of H you were/are. You will get there on the future goal setting and I think it is healthy to start conceptualizing it. But , I agree with ETC that working on you (and your relationship with your kids) is the most important thing. If goals are important to you (and I get it if they are, they are important to me) what goals can you set around you and around your relationship with your kids? Keeping your W and other women out of it at least for now would seem healthy to me.
