I'm confused about a girl

It sounds like she was crazy about you before, during, and after the movies. but then she suddenly changed? like became distant? Or just not too into you anymore?
Maybe you said something to her that upset her but you just don't know. or you offended her?
Maybe you acted in a way that turned her off?
Or maybe she saw you talking with another chick and got jealous?
There are a lot of possible reasons for her odd actions.
Try to go back to the first time you noticed she was acting different. or maybe a time when she didn't seem so "impressed" by something you did/say.
Some girls aren't open when they are mad, or upset. They just play it off, and become distant for days, until the guy finally asks, or realizes what he did wrong. They leave the guy totally confused, thinking . "well, everything was good. the movie was good, the whole night was good. we were doing ok after that. so what happened?"
If you really can't figure out what you did/say wrong, then ask her, "is there something bothering you?". Don't tell her you noticed she's been acting different. Just say, "you seem upset lately."

Oh and major kudos for knowing how you feel unlike most guys :D

It could've just been the atmosphere of the movies that made her more into hugging you and such. If you like her so much and it's obvious she likes you too ask her out. Get the bottom line of how she feels. If she says no to going out then move on because she's a jerk for acting like how she did at the movies and sharing so much time with you. If she says she wants to wait, just be her friend. As in, no holding hands or arms around her because if she really wants that to happen then in the end, ya'll will go out.

I have a guy friend like you too. But for us it's after school, we would hug hold hands and stuff. But during school we would not 'do as much' (like only hugging) as we did when we were by ourselves (not with our friends). When your at school and she doesn't want to act like she did at the movies is because she doesn't know how you felt after the movies or how you are feeling about her period. She also doesn't want to seem too obsessed with you esp. After only a night of the movies and your not going out, but she still hugs you so you would think more of her and to get you to know how you really feel about her. Lastly the texting I agree with catgirl9 girls just don't want to seem eager.

After going on a date with a guy and then seeing them in a different environment it can be awkward. That doesn't mean that she isn't into you, its just that she sees your more sensitive side (and that's not a bad thing) but she may just be adjusting to seeing that side to you. If that makes any sense
don't worry about it and just be who you are.
let me know if you have any more questions!

Well as a girl around the age you probably are this is the advice I can give you. If I went to a movie with a guy and we acted all flirty and cuddly, I would feel kind of, awkward afterwards. I might think I went a bit overboard and I pushed you away. She might be acting kind of more distant that you are used to because she might think she was too clingy that night. There is no doubt she likes you based on all the things she did. She is still hugging you too. It may seem to you she is acting too distant becasue you are looking for stuff she did that night of the movies. And about the texting, I never text a guy back immediately when he texts me, it seems to eager. Sometimes I don't text him back at all just to leave him thinking about me and waiting for a reply from me.

I don't know. Sounds like you might be feeling too sensitive and worried. Is she still talkin' to ya and textin' and such?
