Therein perhaps lies your mistake, telling her all these romantic stuff. Did you ever put yourself in her shoes for one moment and think?
Did it ever cross your mind perhaps that most of the time she receives these sort of 'friendship' for lack of better word? Every guy that wants to get to know her, wants to date her. Few or none guys wants to get to know her and be good buddies.
Ever thought of that? Ever thought of how that would make her feel?
The thing with you is that, the one girl which you went a little head over heels, you automatically think that you're going to spend the rest of your life with her.
From your post, you:
a) Are unable to accept another person's decision (clearly exemplified by your actions despite her decision)
b) Unable to handle rejection (distancing behavior after being turned down)
c) Still confessing business after 1 year and thinking that waiting for her is proving your love to her.
My dear friend, contrary to the popular believe, those actions point more to immature attitude and behavior than anything else.
I'll gladly be the bad guy, in hope that you may learn more about this:
You're not quite ready yet for relationship based on those few responses to disappointments that you faced. There is still much to learn before you should fully commit to someone.
wake him up inside.
