What is a one-sentence summary of the following article?
You already know that you have feelings for this person. If you have not fully admitted to yourself just how strong those feelings are, though, you will need to do that before you can start getting over them. Ignoring the strength of the enemy—in this case, your own feelings of affection will only make it more difficult to triumph in the end.  Even though you never actually dated, you invested a lot of time, energy, and emotion into this person. The depth of your feelings probably reflect this. Resist the urge to brush this off as nothing more than a “silly little crush.” Admitting to the full depth of your feelings may knock your pride down a peg or two, but ultimately, this action will be more helpful than letting yourself stay in denial. There are two main truths you need to admit to. First, the person in question does not share your feelings. Second, your situation is no different from that of others who have suffered the same fate.  Your feelings are one-sided. Even if you know this deep down, honestly admitting this to yourself can be one of the toughest parts of the whole process. You might want to think that something can happen between the two of you, but the fact of the matter is that your feelings are not mutual. Others have gone through the same thing you are going through now. The good news is that this means you are not alone and that you can survive this just as well as all the others who have gone before you have. The bad news is that, odds are, your situation is no exception to the rule. You might think that you can make the other person fall for you, but in spite of what romance novels and movies suggest, this rarely happens in real life. Your situation is far more likely to follow the path of reality than of fiction. Being head-over-heels for someone can be a nice feeling, but after a certain point, that feeling brings you more pain than pleasure. Letting go of the feeling will make you a happier person in the long run. Ask yourself if you are really, honestly happy with the way things are now. Chances are, if you are online and reading articles about how to get over someone you never dated, the answer is “no.” If you are not happy, then the best thing to do is move on so that you can be happy again. The person you adore might say or do something genuinely misleading on occasion, but more often than not, the supposedly misleading things that person does are only misleading because you are desperate for hope. If an action does not express affection on the surface, do not tell yourself that it does so beneath the surface. The vast majority of guys will be obvious about it if they like you back. While girls are a bit more notorious for giving off mixed signals, if you are obvious enough about your own feelings and she does not respond in kind, she is probably not interested in you in that way. The two of you likely have some history of interaction, and you may have let yourself believe that the interaction between you indicated a possible spark. Think back and be honest with yourself about whether or not that spark ever existed. Treat your memories with the same objective eye you have begun to use when viewing your present interactions.

Summary:
Admit to your feelings. Tell yourself the truth. Realize that it is not worth it. Stop reading into things. Review your memories.
