Vise,
Our WW's are a lot alike. She threatens to hold things over your head in order to manipulate you to get her way. Stand firm. She will not love a man she can not respect. If she can bully you around and manipulate you she will not respect you. Do what you know is right. Do not fight over a couple dollars but keeping a budget and tracking spending is important. Pick your battle wisely but don't let her push you around either. Do not let fear keep you from doing what you know is right.

My WW has tried this often. When I stopped allowing her threats to frighten me and stopped bending to her will she eventually has cut way back on the threats.
