You've got some good challenges ahead of you since you work together. One of the toughest parts will be not talking about your relationship or where H stands.
Right now, it's about you being there for yourself and your kids. Your H is on his path and you are on yours. Sounds like you're looking for new hobbies and want to work on your yard. These are great outlets.
One thing that we all learn here is it is most definitely a marathon and not a sprint. Things take time and lots of it. If you try to rush, it will set you back.
All the best.
