Summarize this article in one sentence.
If you're looking to catch someone as a prize or to get someone to go to bed with you, you're treating the person like a thing, and you're probably experiencing lust. Security isn't important to you; you're more interested in the score and in how great it feels to be physical together. After you get what you want, you can take or leave the other person. You're trying to figure out what you have to do to get this person to invite you up for a nightcap. Who cares if you have an argument? You can find someone new without the hassle of bickering, fighting and drama. The sex is great, but it's not worth the baggage, unless it's make-up sex after one of those passionate arguments.
Examine whether you treat the object of your interest as a person or a thing. Evaluate how secure you feel. Analyze the way that you're thinking about the other person. Look at how you handle conflict.
