<human>: Can you provide a brief rundown of the text in within 3 sentences?

My girlfriend [23F] and I [22M] have been together for about 3 years now. We have had our ups and downs, including a short break at the beginning of the 2011 fall semester. However, lately I have been struggling with a few things that I can't seem to shake:

1) I would say my GF is of average intelligence, having graduated college in December with just under a 3.0 GPA. We had a few disagreements about when she should start looking for jobs, which led to her waiting until after she graduated to begin her search (not my idea). Since then, I have noticed a lack of motivation to actually search for good opportunities. She has applied at roughly 10 different places by simply emailing her resume to the listed contact on various websites, and explaining her career desires. I keep pushing her to network by attending local events in her field, trying to find a mentor, or making a LinkedIn profile--but nothing seems to work. She brushes off my advice by stating that she isn't social enough to network, or that it won't help in her field.

2) We've always talked about not having kids for a good 5-7 years after college so that we can have time to DINK (dual income no kids) and enjoy our lives together as adults. However, looking at the current situation I feel as though I am going to be the only one making a decent income, as most of the jobs she comes across pay only slightly better than minimum wage. I'm not trying to be greedy by any means, I just find success and career drive to be extremely attractive in a life partner.

These two recent events combined with a solid year of questioning staying with her have left me very confused. I want to motivate her to be more driven and outgoing, but I fear that its not going to happen. I've considered ending it many times before, but as she isn't outgoing I don't think I could leave her with no one for her to fall back on--I can't hurt her that badly...

Any advice?
