Moving forward happens one little thing at a time.
For me, I started walking my dogs daily, and taking care of the house and two dogs all by myself kept me busy, and now it's about planned maintenance, work is keeping me busy, and so on.
Pretty soon, you spend your time thinking about all of the stuff you are doing, going to do, and the things you now can do, and you stop spening all of your energy on your spouse.
Just let it happen naturally, and that happens one step at a time. What you need to do first are little things to establish a new routine.
