In this episode, it greatly illustrate why I emphasize again and again to not invest in a property with your girlfriend or boyfriend.  What happens if one side refuse to pay her or his part of the installment, just for the sake of not wanting to? The property will get auctioned off and both of their credit scores will get into trouble.  My suggestion would to just stay rational to pay up her share, then try her best to sell off the property as soon as possible, even at a loss. Put an ending to this part of her life and move on already.
