Summarize this article in one sentence.
Look at what you have that a girl could want. From good looks to a nice cash flow or a good car, you could be used for any number of things. You can also be used for your clout, whether it's being a big name on a small campus or even becoming moderately famous. Of course, you don't have to be a big deal to be used. You can be taken advantage of no matter who you are. For instance, if the relationship is always one-sided, such as you're always driving her everywhere, you could be being taken advantage of. See if she only seems interested in going out with you if you take her somewhere nice. Watch if she just wants to just go somewhere where she can be seen with you. She could also be just hanging around to meet certain co-workers. Keep an eye out if she's more interested in that than in just spending time with you. She could also be looking for a free ride, literally, or just someone who will be there when she needs something. That is, some women may use you by only calling when they want something. Maybe they want you to fix something or pick up something for them. Pay attention to when women call and how they talk on the phone with you. If she only calls every few weeks and seems to want a favor each time, she may not be that into you. If she only wants to chat you up at work, she may just be using you to get ahead. You can check by asking her out on a date, but be careful, since work relationships can be tricky. Similarly, if she works somewhere else but only calls you at work to ask work questions, she could just be using you.

Summary:
Assess your status. Assess her desire for status. Watch for needy calls. Check for work-only flirting.
