How do you fall inlove?

When I was at a young age, it was really different when I fell in love. I considered it as a feeling of being in love but now I realized it wasn't yet a love. It was just an admiration. Before if I feel that I am in love, I was so nervous but I was just silent about my feelings. I don't used to cry out loud about my emotions. Once I had been hurt, I would never come back to him anymore. I was scared he would do it again and again. I used to let go. But when I became older, much mature than a teenager, I had changed my vision about being in love. I show emotions but I am careful about my actions. I don't want to hurt anybody. I became more patient and understanding but I didn't lose humor. I don't use to pretend to be okay even if I'm not. I became more considerate. And one thing I learned, I must not let someone go as long as I can still hold on. I would only let him go if he's not anymore happy with me. I break barriers of a relationship such as time,location,rumors,etc. If you are in love, show it. give everything that you feel it is good.
