Settling up Relationships

Computer has been down with adware/spyware bugs since last Wednesday, so it's good to be back - feeling out of touch. My soon-to-be-ex (STBX) who has been residing with an old girlfriend since September 2nd is driving me batty by changing the terms of our separation. First she wasn't going to pay any of the debts incurred on her behalf; then said that was a mistake; now wants me to charge things on the credit cards to get us through until I get back to work and then would like me to help her get on her feet in a new apartment. But, she's now thinking of renigging on her end of the deal, I can tell, but doesn't want to blow the current meal ticket before her next funds come in during January - so, I run up my credit cards, she tells me to pound salt unless I'm working and even then I won't see any of her money - she'll just want me to honor my end of the deal - sounds like a winner, doesn't it. One minute she doesn't want to have anything to do with me and the next she's hugging and kissing me and talking about getting a haircut if I want to get a gal in bed!!? It plays with my mind, I tell you.
