Let me ask you a question, when it comes to love..what do you prefer: feeling or logic? The answers may be vary but allow me to break down my answer of that question.
Love, for me, is a condition when two people care too much about each other and they are willing to alternately give and take from each other. It means love is more than just a feeling. You need action to complete it. When your heart is being hurt by someone you love or when your heart doesn't sure about what you want and what you feel, that's the time your head start to work its function: to think what's right for you, objectively.
I am a logic person, no matter what I do and what I feel, my head goes up first. But there was a time when my head overly lost its power and it got me really down...almost in hell.
I was loved someone I knew for a long time. I didn't plan to love him and I didn't plan to be in a relationship with him at the first place. All I felt for him was care as a good friend, as a brother. But it turned out that the feeling was grew up unexpectedly.
We've been in a long distance relationship for a little while and it didn't turned out good. We broke up and for almost four years, we were silent to each other.
After that, things changed..sometimes we were good again and all I know the next day we were in silent again. It happened several times until at one point I realized.. we weren't meant to be together.
I realized that no matter how hard I try to hold on to him and no matter how long I wait for him , he never fought enough for me. That's the time my head speak louder than my heart. That's the time to move on. I let my head take the decision and take over everything.
So I move on and walk on forward, not backward. It may feel hard at the first steps, but it gets better in the end.
Don't get me wrong, I still care for him. I still care for him as a friend and even now we are in silent again, I still wish and I always wish that he is happy with his life and he someday find the love of his life.
That's how you know when you have to use your feeling or your logic: when you don't feel happiness in your heart, that must be a good reason to start using your head :)
