One of the worst feelings in the world is liking a guy and finding out he does not feel the same towards you. It crushes you, yet you find yourself still obsessing over him. You still really like him and hope that he will change his mind. If you're in this situation, you need to get over him NOW before you hurt yourself even more. Here's how you can do it fast:
Cut off all communication with him
You don't need to see what pictures he's posting on Instagram. You don't need to keep sending him pictures on snapchat. Stop checking your phone. You know you are just waiting for a notification from your phone. A text, a snap, even a picture from Instagram would make you happy, but it never comes. You're waiting for something that will never happen. Unfollow him and delete his number.
Stop creating fantasies in your head
That kind of stuff gives you false hope. You don't need hope. You already know the outcome. You know he doesn't like you the way you like him. Your life isn't over so stop imagining what your life would be like if the two of you were together and instead go live your life.
Stay away from sad songs and romance movies
No matter what you do, don't text him back
Think of all the negative things about him. Was he mean to you? Did he ignore you a lot? Does he like to flirt with a lot of girls? Is he with someone else or does he just not like you? This one guy cannot be the one for you. If he was, then there would be no question in his mind that he would want to be with you. If they want to be with you, they will be. They aren't playing hard to get or trying to get your attention. Get yourself out of that sort of situation and move on. Why would you want to be with someone who doesn't want to be with you? His feelings aren't going to magically change overnight so stop pretending that you have a chance with him.
