Maybe she should be on her own and find away to support herself through school so she can "find herself." She will likely find that life is a lot more difficult on her own, and it might clear her fog sooner. From your post, I don't really see her "trying to make things work." I see her using you for her own ends. She likely doesn't want to be with you (for whatever reason she's concocted), but she's afraid to lose your support. If you withdraw that support, it would be a wake up call to her that she might actually lose you. Definitely detach, either way. Focus on what you want for the long term, and recognize that your W has become a different person. It will take a while for you to see her for the new person that she's become. You may want to work through your issues with this new person, and you may find that, in time, you are willing to release her to pursue her own path and find peace for yourself elsewhere. Best of luck.
