<human>: I'm 24m with a female best friend (24f) who I've known for almost 10 years. I met her when I was dating her best friend in high school, but that's long been over with. We've both had a few relationships over the years but the last 2 or 3 years we've both been single and spending nearly every day together.

Our relationship is entirely nonphysical. It kills me to see her walk away every night without so much as a hug. I used to think it had to do with the way I looked, I started working out last year and have come a very long way (from decently overweight to visible abs) and nothing seems to have changed. I used to be pretty messy and unkempt, and also handled that. No difference. I've got a great career and am very well paid for anyone we know, but I'm not pompous about it. I've spoken to her about it, she says it would just be weird if we got together. I just don't know where I screwed up.

Its not like the only thing we do together is sit around laugh and bullshit, we go see gardens and museums, we went on vacation over the winter and skied places our parents never heard of. We went dog sledding and even saw the northern lights. Not exactly your run-of-the-mill getaway.

I've tried dating other girls, but shes so stuck in my head I'm almost afraid of using her name by mistake. I don't want to stop hanging out with her just to get her off my mind, shes my best friend.

Could you distill the essence of the text into 1-3 sentences?
<bot>: hanging out with female best friend every day for years. Like her a lot but she doesn't feel the same way. Not sure how to handle it.
