Ditto everything freya said (who is evidently a mind reader this morning)
I'd stop taking her calls and stop listening to her voicemails/texts/emails whatever, lawless. She had the best of both worlds before, you know? You paid for things, she could do what she wanted, but you were always there for her to fall back on if she got too unhappy. She has lost her enabler now, and until she finds a new one to manipulate, she may keep at you.
I admire how you think - keep on protecting yourself from this madness. Who needs it?
