I don't think the two weeks in unreasonable, given that it's roughly the last two weeks of the semester. Maybe you're having an easy time in school but she is worried about her grades. After reading this whole thread, I couldn't see the part where she is using you. Are you leaving something out, or are your friends just paranoid and stupid? And she sounds sensible. You are both graduating into a terrible job market. One or both of you might be struggling financially for many months to come, and one or both of you might be forced to move far away for a decent job. She doesn't want this new relationship to become a burden for either of you. That said, it sounds like she hopes that the relationship can continue if you can both land good jobs locally or in the same distant city.
Good decisions come from experience. Experience comes from bad decisions.
