In one sentence, describe what the following article is about:

In order for you to heal, you need space. If you love a girl and she doesn't love you, you can't just go on pretending to be friends. You're not friends: she is the girl you love. So until you have truly moved on from this heartbreak, you need to avoid any unnecessary contact with her.  Consider deleting her number from your phone to avoid calling/texting her. Stay away from places you know she is likely to be. This may mean missing out on certain parties or social gatherings, but it's worth it. If you absolutely must see her (for instance, if you work together) keep your interactions brief and professional. In the modern era, we have our friends at the touch of a button. Unfortunately, this means you have images of the girl-who-doesn't-love-you at the touch of a button too. Although it is tempting, avoid visiting her pages on social media. Perhaps even consider blocking her (at least temporarily). You need the space to heal and you can't do that if you are cyber-stalking her every move. In order to avoid her online presence, you may want to:  Spend less time on social media. Unfollow her on social media sites. Avoid visiting the pages of mutual friends. If you happen to come across her, quickly put your phone away (or close your laptop) and walk away. Don't let yourself get sucked in. If you know that this girl doesn't love you, do not allow her to turn to you for emotional support or physical contact. Although this may be very tempting, it is only going to cause you pain. If she reaches out to you, you must find the fortitude to decline.  You really shouldn't be communicating with her anyway! If she reaches out to you, simply tell her, "I need to take a little space for myself right now. I don't think we should be spending time together."
Avoid contact with her. Stay away from her online profiles. Refrain from intimate contact.
