<human>: Okay redditors, im coming to you guys because I have nowhere else to turn to.

I have been friends with this girl since 2000. We have been hanging out every night until about 2 am for the past couple months. When I come home I think about her, and nothing else, wondering if she has any sort of feelings towards me outside of friendship, picturing life with her as my SO, etc.

She has the most beautiful blue eyes, I get lost every time I stare into them. And perfect, long, blonde hair. She is the only person that I never get tired of. Endless, random conversations, great laughs, and so much more. I could go for days explaining why she is my "ideal girl." 

So, this is why Ive come to you tonight. I need help.. Should I tell her? How do I tell her? Could our friendship end? What if she doesnt like me? What are some signs to look for to see if she likes me?

I have a fear of rejection, and I beat myself up over stuff like this. I cant lose her,  shes the only person I could see myself growing old with. Please, point me in the right direction..

Can you condense the text into a few key points?
