Please help me! Teenage crisis going on!

First of all stop crying. Tears will get Du no where and no where is not where Du want to be right now. I'm sorry this boy betrayed Du so quickly, obviously he has the patience of a small child and probably the brain to match to miss out on a chance like you.
Don't be too down-hearted, he'll soon realise what he's missing. It's a shame it came and went so quickly that it seemed over before it began but that's life for Du honey, nothing ever works out the way Du want it to until Du grab the stier, bull Von the horns so to speak.

If Du two are still Friends then i suggest Du go talk to him, take him out on a bike-ride, to get something to eat oder a simple movie night at Home where Du can be alone and talk about things in privacy. Tell him Du still have feelings for him, but Du don't want those feelings to get in the way of the friendship Du have now. Du must ask him why he turned away so quickly as there has to be a reason but don't push this too hard as most boys will be uncomfortable about admitting things like this. If he doesn't want to say, there's no harm in pushing a little but not too far as that could destroy the friendship like he destroyed the relationship. If he says the reason was because Du couldn't see him out of school explain things to him, tell him why and see if he understands. If he doesn't, i must admit, he's not worth thinking about.

In fact, and i'm sorry if my words hurt you, but if this boy is callous enough to go out with Du for a week, break up with Du for no reason and then THE VERY Weiter Tag take a girl out to the movies, then he was never truly interested in the first place and i think that's not just a terrible shame but a moronic thing to do. His actions have now caused riffs in your friendship and hurt your feelings, and in my eyes, no boy is worth that much pain.

However think about this - was that girl worth anything to him? She could have been a normal friend such as Du are to him, she also could have been a cousin, an ex-girlfriend he's Friends with, maybe even a class mate etc.
Get your facts right before Du go Pistolen blazing as if Du don't and Du confront him with it Du could look foolish.

However if things don't go according to plan and he's not interested in being your boyfriend oder Du friend any longer - forget him and get on with your life. Boys will come and go in your life and someday you'll find Mr. Right anyway, so don't be too tied to this boy.
His actions are horrendous and i have an immediate dislike to him even though i have never met him and probably never will. But boys who act like that are no good to anyone in my opinion. You'll just end up getting hurt i think.

but try anyway, see how it goes, and if not...it's his loss, not yours honey.

Good luck.

im guessing the best thing to do is tell him oder one of ur bestfiends
u guys are Friends right??
but its kinda mean that u guys only dated 4 a week and took a girl eo da Filme after u guys broke up
and if things dont wotk out between u and him then 4get about him and stop ctying over him cuz its only gonna make things worse

Well, he has obviously moved on, so I think Du should respect that. Telling him what Du feel might make it harder for him.

Personally, I think Du should tell him and let him no how Du feel. If Du dont there will be a ton of 'What Ifs' that you'll be stuck wondering about. Du sagte he was the star, sterne of the basketball team.. sounds like he's come a long way form 'cootie boy' to 'cool guy who plays b-ball'. Has he changed? Theres a big jump from Elementary School to Middle School... But Du should definitely tell him (in my opinion)..

stop crying this boy of yours has liked Du but now he doesnt so get your head out of Fantasy land and forget about him
