i need advice.

i don't really know but i think Ты should just be yourself he should like Ты for Ты

There was a movie on this, I don't remember the name... But just be yourself, that's what he likes about you! What Ты wear depends on where you're going. Ты don't need to wear a prom dress to a movie theater, but Ты don't want to wear a t-shirt to a $100 restaurant.

Well, be yourself is the best Совет I can give Ты on how to act.
Don't act clingy или anything like that.

What to wear: Wear what you're comfortable in. Don't try to look older and don't try to look younger, look your age but smart and independant, meaning don't wear anything sluty.

What to say: That is really just be yourself again. Ты have talked all год right? It should be as easy as that. Talk about anything and everything, interests, films Ты do and do not like- stay away from depressing subjects and things like your family because normally people complain and it's a major turn off. So, don't complain unless it's in a jokey way, like wow look at the dinosaur, is it supposed to be real? It looks like a hand puppet!
Sorry, that was lame but it's all I can think of right now.
Good luck!!! if Ты need anymore adivce, just ask!

Well... Since you're 14, I guess he's 14 too? So I don't know his personality или anything, but based on his age, I would say that Ты need to take advantage of your own body. Use what Ты have. High heels may also be something to consider. Ты have to decide what color you're gonna wear, I don't know if you're spring, winter etc, или anything about him, so I can't say much about that...

But the most important things, are:

1. Touch him a lot
2. Always laugh of what he says
3. Give him compliments
4. If he doesn't pay for the dinner, then throw your soda/water или whatever at him and walk away.
5. If he paid for the dinner, then give him a Kiss after the date. If Ты forget it... Poor guy...
