Coping with Bi-Polar WAW

[CountingCrows]

Should I keep this written confirmation just short and to the point? Just repeating that as I had told her, the financial assistance will end on Jan 1, and that she will be responsible for the truck payments/insurance starting in Jan? Do I need her to sign it or anything, or just make sure she has a copy tomorrow morning?

I do want her to face the full financial consequences of her decision, but with us still being married, do I OWE her anything? She is the one who had/has the A and walked out of our lives? She has the choice to decide if she wants to be a part of this M and family. S7 lives with me full-time, so I know there aren't any obligation as far as child-support under the current situation. I guess I need to contact my lawyer again and ask this question, but if anyone else has had experience with this type of sitch, I'd be interested in hearing how you handled it.
