Stay strong, brotha -- I know this is tough on you right now! Water off a duck's back, my friend. Hold your head high, and don't believe anything she says and only half of what she does. Indifference is your attitude when you communicate with her -- pleasant indifference.
Nugget is right about picking a course of action and sticking with it. You haven't been helping yourself with your current choices to have R talks, bring up OM, etc. You are so wise, Heim -- you know what you need to do. Quit letting your emotions overshadow your reason and what you know to be the best action to take. Maybe this new info will finally allow you to back up and see what you have to do. And please -- don't bring up what you found to her. It will look horrible from her perspective. You once again entered the house without telling/asking her, and you snooped through her underwear drawer. That knowledge alone will push her WAY far away at this point. She might even change the locks or just tell you it's over right then and there. Keep this info to yourself, and be content with just knowing that you can't believe anything she says.
Again: (((((Heim)))))
