All about loving a stranger!

It has been five pretty years that i have a crush on someone. It is now that i have told my friends about this. The immediate change that i have seen is that i am no longer the same individual. After revealing so much, i found myself being more motivated to reach for my guy though being shy, but still there is much to be done.
He does not know about my feelings and i am not too sure if he may be liking me. Well, my friends are advising me on that but i am too shy to step further.
On top of that i have read about the incompatibily issues for a Gemini female and a Virgo male. Well, in my case, i acknowledge the fact that i tend to think very much and i do much research work on my "guy" but what to do. I think i love him too much.
Hmmm, i do not know much about him and still i venerate him so much. He is in my every second, i am constantly thinking about him. I do not know if i am right in doing such a thing because if ever he goes far from me, i do not know what i will do.
Really,i love him...what should i do!
