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

Six years ago, I met this girl and we became really close. A few months later, I asked her out. But she turned me down and said she'd rather just stay friends. "That's fine," I told myself. "I can be friends with her."

As the years go by, she and I stayed friends and had a lot of great adventures together. Our mutual friends even pointed out that we had chemistry together. About two years ago, I realized that I couldn't be friends with her because I'm subconsciously fooling myself into thinking her feelings for me will change, even though they won't.

So I tried cutting off all contact with her a year and a half ago, but I kept dreaming and thinking about her until I caved and let her back into my life.

Lately, things have been getting worse. I keep trying to swear her off for good, telling myself that "This time will be the last time I see her." Yet I keep messaging her and hanging out with her (and our mutual friends) again and again. This is torture.

I'm stuck in some stupid friend zone loop. My best friend suggested that I do two things: 1) try Tinder & meet someone new and 2) leave the state so that she'll be out of sight and out of mind. (I'm also trying to leave for career reasons.) I love this girl more than anything in the world and she has definitely left an indelible mark on my life. But I understand that seeing/talking to her isn't healthy and I have to move on.

So that's my story. What do you think? Should I follow my best friend's advice? If not, what should I be doing to get rid of her?
<bot>: I've had feelings for this girl and I keep staying friends with her for years even though she doesn't like me back. How do I get her out of my head for good?
