Puppy Love

1st year uni I met this guy which we will identify as 'D' and I thought he was really cute.
But I never tried to do anything with it - I didn't want to. Why?

He's a friend of a friend.
He was a taski in high school.
He's studying Commerce/Law (addy you might know him, call me ASAP!!!!)
He's an oldest child so he should to be very caring.
He's got dimples!! Dimples are a really big thing for me.
He seems quite shy as well.

And today i had to go to another tute to make up for not going before (i'm naughty) Anyway I rock up and he's the tutor. "my heart is jumping out" He smiles at me in recognition, and there's butterflies in my stomache, a constant shy smile on my face which i don't want him to see.

*puft*
All my confusion from Mr. F and heartache from Y disappear.
*puft*

I'm going to marry this guy. This is my love at first sight. Well I don't love him but I really really REALLY REALLY like him. But then I don't know anything about him. Well I actually do, coz i've been to his house. They wind the clock forward by 15 mins to make sure they don't go anywhere late. His mother is an optimitrist. He's CBA (i think) or at least he has the syptoms of one. He seems shy, gentle, but funny

he gave the example in class:
"if you bought a refridgerator for $1000
and the current market value of the fridge is $100
Which type of insurance would pay you $1000 and $100. And the choices are indemnity insurance and replacement insurace"

and then he adds, he adds:
"yeah.... just in case someone steals the fridge"
and he says it with a straight face and *blushes * a bit and then smiles and my heart just melts thinking about him like that right now.

What should I do? how should I woo him?
what if he has a gf? If he has a gf, I reckon i should ruin their happy home! I'm gonna be a home wrecker, coz i'm worth soooooo much more to be with! (even though I don't know who she is) But then she might be awesome, that's why he is with her. :( And i have a rule about being a homewrecker, i'm not going to be one. :'(
I'm just gonna assume that he doesn't have a gf coz then it would be perfect! (i'm praying to god right now!)
What type of girl does he like? I can't change myself, then it won't be me that he is liking. Does he like girly girls? how do I get his attention? He didn't say bye to me when I left. He wasn't eager. But then he was helping a student. Maybe a look up and wave?
Should I go back to his tute next week same time?
or should I wait a fortnight before I come back so then it looks more convienient?
Should I slip him a note after class with my number on it with an explanation of my undying affection for this man? I'll do that in the very last tute for the semester if nothing ever happens from now until then.
Should i study really hard so that I can ask him questions and ask for help? Would it be a turn on if i'm smart? Coz he's a smart guy right?
Next time I see him, i'm gonna stick a post-it on his back that says "MINE!". I don't think that would be too much right? As long as he doesnt know who put it there.
omg... i shoulds top rambling on. coz i can just go on for days...
