Fuckin-A! 
Animal, no games or stratagies. Be honest with yourself, then go be honest with her, ask her for the same in return. Some blunt honesty can save years of bullshit. She seems conflicted too. If nothing else, you two will get some closure.
For a bunch of alphas, there's a lot of insecurity hereabouts regarding women's attitudes & behaviour. Good of you guys to post up every nightmarish fantasy you ever had about your ex's new sex. "No no, it's 'cause I've been that new guy!" Yeah, yeah, yeah....
If you read the dude's post, the alphas who posted aren't the ones with insecurities. Plus, I sincerely doubt the young lady in question has, is, or will put this much time, energy, and thought into trying to get another person back. Like Stells had said, chica is sending mixed messages, but her actions speak louder. She got another dude. A dude that Big Dick Dan knows nothing about. He could be a dick, or he could be the coolest mofo around. Or he could quite possibly be just like Dan. We tend to fall into patterns and pick the same type of people.
If so, she might go back and forth between the two. Either way, Danimal is right now stuck in a "emotional limbo", he doesn't have her, he doesn't have anybody, yet she has two men in a sense wanting her affections and cooter. Whose in more of power position? The dude asking GB for advice or the chica whose got dudes mind wrapped around her finger?
IMO, what Big Mal, Groink, Ag2, and Stella is the Gospel. If you don't follow it, don't blame them when your feelings get sent to Man-Hell.
