I know it sucks man, she is confused and has really no idea what the hell she is doing. All I can say is be her friend and hope for the best because one day this will all crash down on her and hit her like a ton of bricks.
Either you will be there for her or you will have moved on. Its up to you what you want to do. You cant help her, I have found that out hte hard way, its has to come from inside her. It may take months or years or weeks who knows. Just watch your heart, just like I am. My wife called me lastnight very sad, and we talked but I know this moring she will be back to her old self again and yep she was. I try not to read anything into what she says anymore. Her actions will tell me if she ever wants to get back with me, not her words.
You cant trust anythign they say right now. Sad but true, even tho my wife has been very honest with me I still dont trust her as far as I can throw her.
