You're making progress man. I wouldn't give that woman a cent for a Gucci purse. And bet your bottom dollar she did not cancel her date, she just wants you to believe that so you will cave.
Crazy story for you... when my ex last BD'd me, she was nasty and cruel. She was disrespectful and hateful towards me for no reason, we didn't even have a fight.
Then one day, about 2 weeks before she was going to move out, she became very nice all of a sudden. She was polite and respectful. Then she asked me if would give her $2,900 to pay her back for all the groceries she had bought for the last 10 months so she could use that money to get her new place. I was taken aback and caught off guard but said I would think about it. She remained nice and polite for the next week while I thought about things.
A week later she comes up to me and asks if I had thought about the $2,900. I said I had thought about it and decided I didn't owe her a dime. Her buying groceries was her ONLY financial contribution to our relationship, I literally paid for everything and that if she felt that was unfair, we could put all our contributions on a spreadsheet and see who truly owed who money. The second I told her I was not giving her money, she snapped back in a rage and said "this just confirms my reasons for leaving you!!!". I told her this just confirmed why I wouldn't want her back and I walked away.
My point is that you cannot trust this woman. She will manipulate you to the gates of hell (if you allow her to).
Looking back (I've been NC for 16 months now), I am SOOOOO glad I had the balls to finally not let her manipulate me. If I had given her that money, I would hate myself for it now.
