I just registered to give this advice to anyone who might be reading this and as a response to the post above...
DO NOT, EVER, DO WHAT THEY DO IN ROM-COMS!!!!!!!!!
This is the worst advice in the world and anyone who thinks that relationships work the way they do in movies is going to be alone forever. The advice was given by a girls and my first piece of advice is dont listen to girls. They want a guy whos emotional yet never cries, strong yet tender...Nice guys dont finish. True 'love' never wins, there is no such thing, if you think there is then you are delusional and deserve the horrors that await you. Throwing rocks at a girls window? Stalking charges. Keep trying when it has failed? They will hate you more and more. You have to do the opposite of what girls say they want, or what a nice guy would do. I've destroyed enough relationships to know that sitting round waiting for it to come to you won't work. There is only one way out of the friend zone, not to give a shit about her, but keep her around, fight all your instincts to be a bicth. Do what you want and nothing she wants. Its obvious she doesn't respect you. Demonstrate value while not showing off.
I had an old gf who when I got back in the country she was with a new guy, she didn't tell me and teased me into her bed but wouldn't fuck me, after a year of this I got pissed and saw her for the whore she was, anyway after a few years she broke up with him and I invited her round for dinner, after watching some movie she said she couldn't believe I hadn't fucked her, by that point it hadn't even crossed my mind so far gone was my interest, I tried to fuck her but it was shit, she still wanted me but not I her. Anyway people only want what they don't have, if you show your dedication to her she won't want you, it doesn't matter how nice people are this is how humans work. All good relationships uphold this back and forth.
Rom-coms are written as a fantasy for how people think they should be, not how they are. The fact that your complaining about being friend zoned suggests you don't have the right mindset, drop it and move forward, that is a guy she might like.
