Sorry you are here but you will find out this is a great place to be. Have you read DB/DR books. They are the basis of everything we do here. Your H is starting a journey and you have to take your own trip also. Make the best use of this time that you can. You are being given a gift of time to start to make YOU into the best possible person.
What hobbies have you left behind, take a class but whatever it is do it for YOU!
I will come back later to give you the links to the resources so you can arm yourself with knowledge.
Don't tell WH anything about this site or books. It is your secret weapon.
