Have you read mb28's thread? The same week she changed her MO, and stopped pursuing, her H has started to move in her direction. This is where your best chances are...stop pursuing, Take a stand. She is not running yet, all you have to do is make her turn around. The only way to do that is to enforce your stand against OM, and YOU turn the other way. She will then turn to see why you are not pursuing her.
