You are wise in not discussing divorce and the details, i.e., especially w/the holidays just around the corner. Well, she will need to make up her mind on working/college. You may end up having to support her while she's working, but there shouldn't be a problem with her having a part time job and going to school. You will need to check out what your responsibility in the way of funding if she opts to take the school route.
I am so sorry you are having to deal w/this. It's never easy when a spouse is confused and doesn't know what he/she wants to do.
I do agree w/Peace, once the divorce is finalized and the dust has settled, a huge weight will be lifted off your shoulders.
Hang in there!
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.
