Stop asking her, "What's wrong?"

STOP COMFORTING HER!

CUT OFF THE MONEY!! NOW.

If she throws a hissy, TOUGH!! And DO NOT DEFEND, EXPLAIN, or otherwise try to REASON with her.

The last thing you want to be is her GOOD-FOR-NOW-GUY.

You are making it easier for her to continue her disgusting behavior, and in the process, you look weak and unattractive to her. Women find wimps pathetic.

So, for the love of God, stop. Just stop. Please.
