How can she act so innocent like when she's been toying with my emotions? I can't stand the lies. I know, maybe its a case of "ask no more questions, I'll tell you no more lies" but damnit, it has to stop sometime!
First of all, she's not toying with your emotions, she is probably just dealing with hers. Let me ask you this: What if she told you "Rob, ok, it's true, I have still been seeing the OM since I've been back. He did buy me the necklace. I am still conflicted. I still have feelings for him but I know I want to be with you. I guess I am still working things out. Again, I want to be with you, I know that but I am having a hard time just quitting him." What would you do? Would you tell her to leave? Would you issue an ultimatum? What would you do? I ask because that may be what you hear if you push her. It could be worse, but likely that is the worst going through your mind, right? Does it change anything? Only you can answer that question. Like you've heard a thousand times, only you can decide when you've had enough. Just make sure you make that decision when you decide to, not when your emotions do.
