How to get my ex-girlfriend back?

I was with her for ten months. We were both each other's first boy/girlfriend, lost our virginity to each other, and shared amazing moments together. We're in a long-distance relationship now that she's in a college about three hours away.

It's only been a week and she breaks up with me last night saying things like:

"I want you to be happy with somebody else who you can see more often"

"I'm not sure if I love you anymore"

"I need some space"

I'm so hurt. I did not see this coming at all.

I know, it sounds like it's dead and over. But if she loved me before, she can love me again, right?

Please help! I really miss her and I don't wanna lose her.

We still remain friends, and we're really close, and I was planning on visiting her next week, and she said she'd still like it if I came.
