Bobcat - Welcome. Sorry you find yourself here. Sounds like you've started off on the right track. Especially in the case of working on yourself. It's important when you work on yourself to focus on being the man YOU want to me. Don't do it just to please your W. This will help the changes be more permanent. If you are working long hours, as a 180, you may want to consider cutting back on your hours. Your W may feel like she is competing with your job. As far as giving space, just keep it distant but interested. If you can scrape up the money to enlist a DB coach, I would highly recommend it.
Just my 2 cents. There are some vets on here that may be able to give you more.
