Wondering Why She Isn't the Person She Used to Be, I am having problems with my girlfriend... Options

[Pendragon]

Alright, so the sole reason I even got this account was so I could ask for some help on my relationship issues, I've asked friends, family, BEST friends, and just plain asked myself as to why things are going the way they are going with my girlfriend and I... But hopefully this experience will prove worthwhile and then I'll be dedicated to the site! (crosses fingers)

I've been in this relationship for going on 8 monthsnow and it was absolutely amazing in the first couple of months. I was an 18 year old at the end of my high school year and had never really wanted to be in a relationship with anyone. There had been opportunities, plenty of them, but no girl had just screamed at me "THAT'S HER!!! THAT'S THE GIRL!!" Im very very picky when it comes to my women and if I wanted to be in a relationship it had to be with someone that gave me that vibe.

It was the first day of school and I walk into my next class and sit across from this gorgeous girl (current girlfriend) and I was so breath taken by her beauty I was so damn nervous to talk to her for about two weeks haha. But after finally conversing with her, we hit it off amazingly finding out what we had in common, what the other's lives were like, our pasts, what we aspired to become and make with our lives... She was a junior in high school, senior now.

But after a rocky relationship with her ex and best friendship with me, she finally called it off with the other guy and I admitted my feelings for her. She accepted those feelings and I was absolutely ecstatic! Things were great for the longest time! And when problems happened, we talked about them. Now, to be sweet and cute, I always had celebrated our 'montheversary' by giving her roses included with a card and a summary of our relationship thusfar.

I've given her so much over these last 8 months... But now.. It's her senior year and I'm working all the time. We hardly see eachother, she now claims that she has a problem talking on the phone to me... She only texts me about once a day and when I ask her why, she tells me to get a life. I feel like I've done so much for her and I'm not really getting repaid for it...

I kind of have the feeling this is all on account of the fact that.. It's her senior year, she wants to have fun, but not with me because she claims I "bring her down" and that I annoy her with all of my "constant texting"... On average I'm texting her 2 or 3 times a day. Again, I just feel like I've done alot for her and I'm not really being compensated for it.. She's my best friend...

It makes me angry knowing she doesn't appreciate me anymore..

Am I being selfish? Needy? Is she not caring anymore? Does she want some space? I just want things to be happy for us again... So please, anyone, before I confront her about this can you tell me what I should do, who's right or who's wrong if either of us?

Thankyou,
