OK, what I am about to say is going to be harsh but it must be said.
The chorus of voices here have said almost exactly the same thing, move along, let her go, move on. Being in the situation, as thmilin said, is much different than being an observer as the rest of us are, there is sense made in both camps. But you continue to torture yourself with her presence in your life. You may not want to hear this but letting her go is probably the best thing for both of you at the moment.
If there is a choice between losing your sanity and losing her, she looses, hands down. Sorry but self preservation alone should prevent you from exposing yourself to this pain. Either she is playing you and your feelings, or she is playing herself by manipulating your feelings to make her feel better about being alone. She may, in fact be genuinely confused, of this I have no doubt, but why pull away from someone who you really love and who really loves you? We are all, to some degree immature. We all want things too difficult to find alone, in the guise of someone else.
But the bottom line is this, the push and pull, the back and forth has increased since you have forced her to come to terms with a distancing. You have to ask yourself why, if she loves you, is she only willing to show it under these circumstances. And if you ask us, you need to consider the very real possibility that on some unconscious level she is playing you, and herself. A break does not mean a free pass to confuse, dismay and cling tighter. It means a break. The provocative nature of her messages seems very odd to me, like she is using her sexual appeal to rope you in, and that is hardly fair, or right.
