<human>: I'm a professional at my career for the last 7 years and she's just joined us mid-2014.

When she started working with us, I got a bit swept up and attracted to this girl - lots of great traits I'm looking for in a partner. Her personality really lights me on fire. But she's a coworker so I've kept things strictly professional.

Now 6 months have passed and it's only gotten worse. I figured, oh, it's just lust or puppy love. Look for something wrong with her and exaggerate it. Didn't work. I've tried to find things to not like but I feel like I'm just accepting them (like you would if you were really dating someone). I've tried to keep topics professional at work too but between the both of us, we keep getting into personal-life stories and the conversations just flow. She asked me out to lunch today (in 7 years, I've avoided going out to lunch with almost any coworkers) and honestly I didn't want to go back to the office. I just wanted to keep chatting it up. . .

Worst part, she has a boyfriend already and I am NOT the kind of person to interfere. These lunches are about as far as I'll allow myself. 

So here's where I'm stuck. She's impossible to be with. . . and yet the boyfriend thing doesn't really matter to me because people split up all the time. And the coworker thing doesn't really matter to me because all kinds of folks have found their SO at work before.  

I respect her situation and am not going to interfere so long as I know she's involved with someone. . . but it's just never really been this hard to get over someone?! Really?! Yes. . . 

My question: You're falling for someone, you're falling for the right reasons, you even get to see them every day. . . but you're not allowed to be with them. How on earth do you "get over them"? 

My biology sees a great match and my head won't listen, months later, try as I might. Thanks for the advice!

Can you provide a brief overview of the text?
<bot>: Met amazing girl. But she's my coworker and involved with someone else. What tricks do you folks use to get over someone who's really caught your attention?
