Is this girl using me or just confused? She will not tell me how she feels.. help :/?

Why do we keep doing this to ourselves? We are the dumbest. There's no female on this planet that's worth all the hassle that we go through. I gave up girls 7 years ago and decided I was just going to be by myself the rest of my life and I have to tell you this along with going back to college and getting my degree has to be the best thing that I've ever done. Good luck with whatever you decide but I would leave her alone.
