<human>: Can you give me a shortened version of the text?

I have been dating this girl since early January. We immediately hit it off well, started dating, and since then we have seen each other almost every day. We haven't had any fights, we haven't done anything sexually, we just enjoy each others company. 

I find her pretty attractive, not just sexually, but my main problem is I have never felt a spark. Normally when I kiss a girl for the first time I feel something, but with this girl I have just been comfortable. I feel we're more friends who kiss every other day than partners. 

I know this may seem like some dumb teenage romance, and it probably is, but she's such a nice girl. The only thing holding me back is I'm the first person to truly care about her. Her depression went away when we started dating and her mom says she has never been this happy. I don't dislike her, but I just feel our relationship is boring.

She is going to college next year and I am staying home to work and save up money, then move into the military. It just doesn't seem like it is going to work out. 

When I'm in the halls I talk to some girls or "eye flirt" and I feel something, that weird honeymoon feeling that I've never felt with my girlfriend. 

I know the saying that you can find the right person for you but you won't be the right person for them, I never thought I'd be on the not happy side of it. How can I come off nice? How can I not break her heart? I don't want to hurt her, but I want a relationship where I actually feel something.
<bot>: My girlfriend has never been happier in a relationship, but I do not have that same happiness. How can I not break her heart or not come off as a dick?
