<human>: Give me the gist of the text in a nutshell

So there's a girl.
As usual.

I met her like 5 or so years ago. And pretty much instantly fell for her. She's funny, and quirky, and original and beautiful. So beautiful.

We hit it off really well when we first met. But nothing intimate happened. No kiss or anything just a hug goodbye. 

Anyway a little time passes and we start to hang out a lot. I get more interested. And more interested.
And eventually somehow pluck up the courage to tell her that I really like her. Turns out it was super obvious - and that she wasn't into me in that way. 

So I bail. Basically. Over the last 4 years I've dated another girl (now broken up/entirely different story) and have changed heaps as a person. Lived in another city for 2 of the years.

Anyway recently we made contact again. Me and this girl. She's done heaps also. Travelled the world. Dated a guy. Acted in movies. Heaps.

And I'm back to being interested in her again... (more than friends) 

I have ABSOLUTELY no idea what to do.
She seems to enjoy hanging out. But is never the instigator. (Whether that's personality or she doesn't care for catching up, I don't know)
Some parts of me are saying I should just straight out tell her again. 
Other idea is to just be happy we're friends. 

What do you think my dear Internet?

<bot>: I'm falling for a friend. Again. She already rejected me years ago. But things have changed. What do I do?
