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

I can't seem to think straight or "be myself" around girls I consider attractive. It's only girls who are in relationships. I've got a pair of friends who are dating, and I'll use fake names and call them Daniel and Emily. Daniel is my best friend in the whole world, and his girlfriend Emily is just outstanding. It's seriously a "Best Friend's Girlfriend" or "Jesse's Girl" situation. I find myself wishing I was him, wishing I had her. I could go into greater detail about this girl, but in the interest of keeping this short, I'll just say that I actually tend to do this with just about any beautiful girl I meet who is in a relationship with a guy. It's not just Emily. 

I just joined an intramural kickball team, and the shortstop is stunningly beautiful and has an amazing personality ... but she's dating the third baseman (who is also an awesome person). Same thing happens with a girl I know at work, a girl whom I'd steal away from her douchebag boyfriend in a heartbeat if I could. 

My mind just kind of races when I'm around women like this. I find myself staring at them, but I'm pretty certain I'm not creeping on them at all. On the outside, I'm perfectly social and I act appropriately, and I've NEVER acted out of line in any of these situations. I know this is the case because all three of the women described above are still friends with me and they talk to me normally. So please, don't get the impression that I'm some weird guy who drools over other guys' girlfriends, or stares at their tits, or anything super creepy like that. What I'm describing is just an internal struggle. I'm having a hard time MANAGING MY INTERNAL ENVY. 

And if it wasn't already painfully obvious, yes I'm single. Yes, I'm trying to date women. No, I haven't had much success lately.
<bot>: All I want to do is allow myself the freedom to be in a room with unavailable women and not get all flustered inside my own head over the fact that I can't have them.
