Don't keep quiet!!! Ask her for the money and the stuffs ASAP!!!
my used-to-be very close friend in Thailand once did this to me also. She borrowed my money and didn't return in time and kept avoiding me.
What I did is I went to his Dad. He's quiet big in the society. I went to him, told him everything and also how to raise his children to be a good person in the society. I got the money immediately after that.
Money can easily turns a "friend" into a "fiend" ka. When it comes to the money issue, U have to fight for that.
