Girls why dose she so this?

Sounds like you fill a void in school, but after school she has other things to do. Looks like you're misreading her intentions, or it's just wishful thinking on your part.

That is really weird. It is possible that she just doesn't like texting or anything like that. Does she talk to you a school a lot and enthusiastcally? Dos she come up to you and start conversation or do you always go up to her? I was just wondering because there was this boy at my school who had this huge crush on me and he was alright but I would never date him (just because I found him to be a bit annoying and he always had a bit of a dirty appearence) and he would always come up to me after class and start talking to me. I always talked back nicely of course because I didnt want to hurt his feelings but when ever he texted me or instant messaged me I would ignore it and just pretend like I never got it. I hope that this isnt what your girl is thinking but I don't know. I really hope it works out and that I helped. Good luck :)

maybe she has a good reason you will only know if you ask.. just play it off and be like heyy you didn't text back last night.
