Matt, you need to understand something fast. You cannot fix them or help them. Don't even try! You offered, she refused, no problem! Let her fend for herself. The less contact you have with her, the better you will be. OK, you made a mistake in filing the taxes.... I'm not sure you are as much at fault as you are telling. If I understood you correctly, you W at the time failed to claim the proper deductions. Anyway, let her do whatever. Take a step back and look at things, every time you get around her or talk to her, this is what happens. Save yourself a lot of pain and aggrivation and simply stay away from her.
