Welcome to the "other side". Sounds like you are turning a corner. Remember that you don't "HAVE" to get divorced. make sure it is what YOU really want. My lawyer told me it was important to get a financial agreement but the divorce is really just a piece of paper. It is so true. BUT...
I really did move forward faster once I got the divorce. For me - that was the finality I needed.
Don't worry about a Rebound guy just yet. Take time to heal yourself before you think about someone new. Find yourself again. learn to enjoy being single. Remember the things you loved before you met your husband. Activities. Hobbies. Whatever - make sure you find joy. Get your groove back.
Good luck and there are many here who can help you as you go through your recovery.
