Ambivalent, Not being nosy, but won't you need a license to operate out of your home? You might want to check on that before lining up customers. Also, you'll need liability insurance, just in case someone sues you. I'm sure you've already thought of these things...but wanted to make sure you didn't forget them.
I'm glad the insurance came through, but please remember, it was marital property and he may ask for half of what you get back from the insurance company...I know, I know...he left...but there's no official paperwork and until things completely shake out...you never know what he may want or not want from the home.
Food for thought today and sorry if my thoughts bring you down, but I'm looking at things a bit differently and want to ensure that you are taken care of and don't make costly mistakes along the way.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
