There are multiple scenarios that can happen in these situations. You fell in love with your best friend and the feelings weren’t returned. You went on a couple dates and you thought it was going somewhere but they apparently weren’t. You have been pining after this guy at work and finally muster up that courage to find that he is by no means interested. This scenario is always the same just with different facades. How they happen runs along one of the same stories, but our responses to them can vary greatly. If there is anything I have learned in these situations it’s that you can’t keep being rejected from happening, but you can control how you react to it.
One way I have seen people react is via getting livid with the other party, trying to delete them from their own lives to create the satisfaction of winning. This is the wrong response. All you are proving is how immature you are. It is never necessary to remove someone from your life unless they are going out of their way to be toxic to you. If you grow to realize that the other party had no choice in not liking you, then you will learn to reserve your anger for another day, and move on. Hard feelings never get us anywhere.
Another way I have seen people respond is through pining harder. You get rejected once, but surely if you just stick around and show how hard you are trying and how dedicated you are, he will turn things around, right? No. It only appears as you are desperate and unwilling to accept facts. He’s just not in like with you, that is likely how it is going to stay. So instead, try to move on and prevent further damage.
There are however, many more appropriate ways to handle the situation. The first step you take is defining the relationship. You need to ask “Is this relationship going to happen, or will it never happen?” You need to do so so that you can get the hard “no”, and not be strung along. Once the hard no has been given, thats it, you will never be with this person. Once you get the hard no, you need to accept it. This can be the hardest part. You just have to learn that there is no point trying anymore because it is a lost cause, and there is probably a better relationship out there for you anyway, you just have to keep looking. Lastly, move on. There is no reason to be bitter, things just happen the way they are supposed to happen. The sooner you accept this the sooner you can be happy. You could even remain friends with the other party if you can move on.
The most common thing I have seen online on how to get over a guy is to delete him from your life completely, I don’t think that’s the case. You can do just as well by accepting and taking time and moving on. There ARE more fish in the sea.
