If you're divorced, tell her she isn't your responsibility anymore, as was wanted. It's not uncommon at all for people divorcing or freshly divorced to get nasty with the other. I would suppose it's not uncommon to feel territorial over the other at times, as well. My guess is that if anything, she's feeling jealous because even divorced, part of her still tihnks of you as hers.
