People please help me with this girl

Okay, so there is this girl that im in love with and shes in love with me well thats what atleast she says.I am only 15 years old but I really got feelings for this girl. But she hurt me a lottt of times. Once on our way back form a senior trip (at that time I really liked her and she told me she really likes me) so at that day I told her im in love with her and she was like oh okay and then l8r on she was kissing with my friend and she told me she did that so he would leave her alone because he was trying 2 hook up with her. I was really pissed off at her that I turned away from her when she tried 2 kiss me goodbye that night. Then l8r on she tells me shes in love with me too. And a lot of stuff happened between us shes a virgin and I had sex a lot of times but I wont let her have sex because shes just too young and I know she will regret it in future. Then a lot of other things happen that hurt me. For example she would always do the same exact things she would do with our friends who are guys for example she would jump on them and hug them and kiss them on cheek but then I got mad at her and she stoped and also before fell in love with me she told me she likes another guy since she was like 5 and she didnt know if she still liked me so basicly she liked me and some other guy meanwhile I told her im in love with her.but then l8r on she got over him atleast thats what she said. so l8r on I keep gettin hurt from all these different things. She has my aim account, my myspace account and everything she needs I give her it and I got her myspace account but once we were kidding around and I said she should give me her aim account and she was like nooopeee as a no and trying 2be all innocent also be4 that she asked me a weird que she said promise me that ull always be my bestfriend no matter what. So I started asking her what the f*ck is going on and she said nun and shes nun hidding anything away from me and now I looked at her funadvice page and she never told noone about it and like I c these guys she comments saying your gorgeous and stuff like that. Also I would have went 2 russia this summer I had the money for it and everything and I miss my family very very much and she told me she wishes I wouldnt go and id stay with her here
So I didnt go I told her I have no money so im staying here but now she goes 2 camp and I didnt c her for a month already we barely talk and we dont c each other meanwhile shes wid sum other people going 2 diff places and stuff like that and shes saying that she misses me and she only needs me in her life and everything. So what do you think should I do? And what do you think shes doing? And does she love me? Because I told her if she got sumone else idgaf I can move on and find other people

Ok it sounds like this girl does not know the true meaning of the words, "I love you." She may be a great girl and everything. It sounds like she is a little confused in certain areas. I was ok with everything and going to give the needed advice to the best of my ability until I discovered you said she had said, "Promise me that you'll always be my best friend no matter what." That to me is saying that she does not like you more than a friend. If she does she is having a heck of a way to show it. I think you should move on. I mean you've made some hard sacrafices for this girl and she is un-appreciative. Missing a trip to Russia for her? That's tough love but her being totally unappreciative about it? That's crap. Sorry to say this bud but I think you should move on. It is going to hurt for some time but I believe it's the best thing.

Wow... she was kissing someone to make them leave her alone? Thats really lame and I'm not buying it. It just sounds like shes confused and doesn't know what she wants, she changes guys like I change underwear. As for guys commenting her pictures saying shes gorgeous, she cant control that. I have guys commenting my pictures to, doesn't mean anything personal. I definitely don't think she loves you, if she did all this confusing stuff wouldn't be going on. She doesn't respect you at all by the sounds of things, you need to move on and find someone who is worth your time and effort.

I say leave her.
shes really immature and doesnt sound like she deserves you.
& I deff agree with stephanief987.
if she did really love you, this stuff wouldnt be happening, and she wouldnt have done the things she did.

You both need to know the meaning of the word "love" . You two arent even in a relationship, and your acting like you are. She obviously loves the attention she gets from boys, and just sees you as one of her many admirers. She wouldnt be someone very trustworthy, and seems too immature for any kind of relationship. I personally dont think she feels the same way about you as you do about her.
