Need help with long troubled LDR....

Hman

My girfriend and I are having some problems. Here is the story.
We were best friends for years since high school, and I guess fate had its way. We had always talked about how we'd never work out, yet other people saw us together, and countless people told us we'd end up together, including her parents.

I graduated high school early and joined the Marine Corps. She and I wrote letters back and forth in boot camp, and I looked forward to them every day. I graduated boot camp and finished my first 2 schools a few months later. During that time we had hung out and been ourselves, I went home every weekend and was at her graduation, but I could tell something was different.

We were long distance friends at this time. We were talking one night and she admitted to have had feelings for me since boot camp. We talked about it for some time, and ended up together. We have had an amazing relationship that has lasted for going on 9 months. We talked every night for hours, always laughing and smiling and loving each other. When we were together, we spent every minute with each other, never getting tired of the other. It was the perfect relationship in my eyes, I couldnt have asked for more. We were on top of the world and we loved each other so much.

It has been a Long distance relationship but we have seen each other at least once a month, and everytime we're together it is just amazing and so worth it. We are always intimate and loving. She had never had sex and was insisting on waiting, but we finally had sex at 6 months, and she always tells me she has no regrets.

We were talking on the phone recently and she told me she was feeling different and that she was confused. She had thought of breaking up because of these feelings and that she doesnt know why she's having them. She says she still loves me but doesnt feel "in love" with me anywhere. She came out to see me this weekend, after valentines day. Things started out kinda wierd. The first night, We slept in the same bed and everything, but there was no love at all. We talked it over and we both cried that night. The next morning we woke up and all of a sudden things got bed playful, we were kissing, intimately at times, and even took a shower together. We went to hollywood to sight see and things changed again. there was no holding hands, kissing in the elevator, no i love yous, and later that night she told me she was uncomfortable getting intimate right now because she's confused. I'd tell her I loved her and she'd reply with nothing, except once saying i never said i dont love you. We talked again that night, cried, and woke up the next morning.

the next morning things didnt get better. We hung out in san diego, same things happened, no intimacy. We talked at a beach in san diego that night, for a long long time. She says she is confused and just wants space right now, wants to take a step back, possibly date other people, be open..... so we agree to stay together but openly until she comes out in another month for spring break. We go to the airport, kiss several times, and she goes off.... She went on the plane with the roses I got her.

Now I know this is a very long post, but I want some opinions. is she just having college stress? feels lonely in the lDR? Will she most likely realize what she's done and want me back? I need help. I love her so much and I don't want it to end. We talked about getting married so many times, where we'd live, kids names, etc. But not till I get out and she finishes school. She is not a party girl, not one to hurt anyone, she is so smart, but I feel her emotions are blinding her. She said the feelings have nothing to do with how I've been or anything I've done. Thak you so much for all the help.
