This is the power of the human face and the human regard, and the meeting of the eyes is as magic a connection as can be made on this earth, equal to any amount of electrical shock or charge.
We all go through a similar experience like this eventually in our lives: Getting hurt from hearing the truth. I’m sorry that your efforts in trying to get his attention didn’t work. Just know that depsite being broken, you can still be fixed. You may even benefit from this situation, learning from your mistakes and opening your mind to many more things you never really thought about. It’s okay to not know what to do; you don’t always need an answer of what to do, though it would be nice to have an answer. I really wish I could help you though. I went through a similar situation and overall, I never found myself with an answer.
What I did was distract myself. I know that isn’t always a good idea, but depending on who you are and how you function, the way you heal will differ. I recently liked someone immensely and well.. he didn’t return the feelings. And yes, I hated what how he made me feel, but I didn’t hate him. Because he was a good person, he made me happy, and that’s why I liked him. I’m not sure why certain people end up in your life, but you did cross paths for a reason. If it isn’t him, then maybe him leaving you is opening a door to a new person, a better person. But you won’t know until you let time take its way.
