Please help me! Teenage crisis going on!

First of all stop crying. Tears will get あなた no where and no where is not where あなた want to be right now. I'm sorry this boy betrayed あなた 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 あなた honey, nothing ever works out the way あなた want it to until あなた grab the ブル によって the horns so to speak.

If あなた two are still フレンズ then i suggest あなた go talk to him, take him out on a bike-ride, to get something to eat または a simple movie night at ホーム where あなた can be alone and talk about things in privacy. Tell him あなた still have feelings for him, but あなた don't want those feelings to get in the way of the friendship あなた have now. あなた 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 あなた 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 あなた for a week, break up with あなた for no reason and then THE VERY 次 日 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 あなた are to him, she also could have been a cousin, an ex-girlfriend he's フレンズ with, maybe even a class mate etc.
Get your facts right before あなた go 銃 blazing as if あなた don't and あなた confront him with it あなた could look foolish.

However if things don't go according to plan and he's not interested in being your boyfriend または あなた 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 または one of ur bestfiends
u guys are フレンズ right??
but its kinda mean that u guys only dated 4 a week and took a girl eo da 映画 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 あなた should respect that. Telling him what あなた feel might make it harder for him.

Personally, I think あなた should tell him and let him no how あなた feel. If あなた dont there will be a ton of 'What Ifs' that you'll be stuck wondering about. あなた 発言しました he was the 星, つ星 of the バスケットボール, バスケット ボール 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 あなた should definitely tell him (in my opinion)..

stop crying this boy of yours has liked あなた but now he doesnt so get your head out of ファンタジー land and forget about him
