<human>: Give me a shortened version of the text

There's a girl my age that I've known for five years and we're in love with each other. I'm a relatively young (nineteen) guy and I know that when a teenager self proclaims themselves as being in love with someone, it can kind of be a natural response to scoff at them, but hear me out. I've come to appreciate being friends with someone before you date them, so it wasn't until my best friend became a lovely woman in my eyes that I started going out with her. In the first two years I knew her, we dated on and off. There was a lot of self discovery and learning about the other that only made us closer, and we always seemed to find ourselves back together again. Now we've been together for a consistent three years, and up until recently, totally in bliss with each other. Now here's the dilemma: She loves me and I love her, but says she can't do a romantic relationship right now. She's interested in things like travel and talks about trying new things (including girls). She tells me 'You're still the one I want to end up with' but it's excruciating when I know (from friends being there) that she's kissed other guys when she's been away on trips. What's the point of ending up with a girl if you don't take the road there with her? There's no one else that I want to be with, but it really gets at me when she doesn't want me to be with another girl--while at the same time fooling around with other boys (no sex as far as I know). This girl really does love me but sometimes the byproduct of how she is gets me down. I don't want to leave her because we've been best friends for five years and I'm in love, but feeling like an unfinished book on her shelf is killing me. Have any of you been in a situation like this? What does someone do when they can't live with or without someone like this?

**This is a large part of my life that I tried to compress into the confines of this small space and the reader's attention span. Sorry I couldn't bear/manage to put this into
<bot>: There's a lot of history, facts and feelings on both of our accounts that I could elaborate on if need be.
