I saw this on Pinterest recently and it couldn't be more true. You might be the best of the best or the sweetest of the sweetest and there will still be someone out there who doesn't like you.
I have a friend who gets upset every time she discovers someone doesn't like her. She always responds with, "They have no reason at all to not like me." I mean, they obviously found one reason not to like her, but it doesn't really matter in the end. You just have to accept that they would prefer to not have you in their life.
That's the thing to remember, too. Why should you spend time worrying and fretting over someone's reasoning for not liking you? If you know the reason, are you going to change? Or will it make you more upset at that person because you don't agree that it's a good reason to dislike someone?
In college, I had a friend who I felt was one of my closest friends for years, but things were beginning to change. Slowly I realized that she wasn't answering my texts or phone calls and didn't ever want to hang out with me anymore. At first, I was offended. I remember saying that she had absolutely no reason to not like me anymore. I obsessed about why she didn't like me for months. There came a point where I honestly didn't care about having a friendship anymore; I just wanted to know why she didn't want to be friends. I'm not sure what happened to make me realize that I needed to let go, but I finally did. I remember one day I just accepted the fact that we weren't going to be friends anymore and I will never know the reason why. The reason didn't matter. I figured out that I shouldn't keep making myself upset or unhappy over someone who clearly did not want me in their life.
Now when I hear that someone doesn't like me, I remember that there are other people in my life who care a lot about me and I should spend time thinking about them rather than someone who isn't spending their time thinking about me. Next time you find yourself in this situation, just remember that. As I always say here on this blog, life is too short to be unhappy. Don't let someone else control your happiness because they found a reason to not like you. Remember, someone who chooses to not be a part of your life allows you more time for others who want to be there.
