Thanks for the update. It sounds like you are just dealing with life. Everyone (Divorced and married) deals with these issues. Yes, it would probably be easier if your husband was still in your life, but I have several married friends who are going through the exact same teenager / money / job issues. You are handling it as gracefully as anyone I know.
I am surprised that you have not moved forward with the divorce paperwork. I know you are busy, but is it really a time issue, or is busyness your avoidance mechanism? Personally, I know it was easier to detach, and move forward once I got the official divorce behind me.
Kudos on handling Thanksgiving without any drama. And again, thanks for the update.
