Thinking back, I realized that I kept going back and forth trying to abruptly show my feelings because I was afraid that he wouldn't provide any feedback. That's not right. When you love someone, you shouldn't wish for any feedback, no? Also, communication is really THE key. I found out that I'm quite hard to keep up with updates while he always managed to do that no matter how busy he was. Perhaps, I should try to love someone more properly next time, unconditionally devoting myself to them.
