Benson, I've been following this thread from the sidelines till now, but feel compelled to comment due to recent developments. In my opinion, it is a large mistake to show Aya this thread because it will send the wrong message.
When you are uncertain of something, there are two things you can do: 1) do nothing but hope for the best. 2) act and find out. Until now you've basically been at (1) and now you're trying to move to (2), but there are risks. This risk consists of the chance that she tells you in clear terms that she does not feel the way about you that you wanted her to. Other possibilities are that she clearly does like you a lot, or an unclear statement either way.
It is laudable that you want to act, and understandable that you waited a long time for this. After all you seem to sincerely like this girl and a rejection would definitely hurt you. However, the nature of her feelings towards you are already set. There is not much you can do to change these. All that matters is that you are clear about Aya's feelings for you.
So you want to elicit a response from her to get some clarity. At least you want to be sure that she doesn't break communications for 4 months yet again. Now you assume that when Aya reads this thread, she will understand how you think. I think she will understand that you are a dreamer. There's nothing wrong with that, but it doesn't seem very appealing to a girl, I think (it's different than being in touch with your emotions, which they do dig). It also tells her that you are too lazy or scared to tell her in person (a letter in fact) that you enjoy her attention.
For that reason, and also that she might get suspicious that you set some of your posts up more as confessions than as contributions to the thread, I strongly recommend you not to show her this thread. Instead, I would in your case write to Aya that you enjoy her replies, and talking to her. It doesn't even have to be a letter with that theme, you could also write it as a side-note in some other correspondence as long as its clear you value her. This should not be harmful as long as it isn't done too cheesy. You could post a draft and we'll evaluate it for you.
cheers,
Demian
