I'm not sure I understand what you're asking, Jman. Your first new post, you lay out everything how you feel she's playing you, and having an affair, and the next post you say you don't want to do anything different because you're not sure whether or not she's having an affair??
Would it be a dealbreaker if she was?
How LIVID are you prepared for her to get if you take a stand?
Think hard about those two questions. Also, go back and read your old thread, if you haven't done so already.
