I've noticed a lot of guys (and girls), really start to make dumb decisions the moment they get 'friend zoned' or even simply shown a slight hint that other party isn't that interested. Where instead of backing off they feel the need to turn up the heat and try to pursue things further.
Don't do this.
If she doesnt want things to go further, don't waste a single second further on the relationship, unless you also want to just be friends.
Don't take it personally.
Don't get upset.
Don't even think about it. Be happy... move on.
Not only is this good for your personal health, but it also keeps your dignity in good tact.
And has the side effect of actually boosting your SMV (Sexual Market Value for you young players).
When you see the girl who friendzoned you, don't be angry, don't be awkward, don't be upset, don't be shy. Be happy and social.
Anyway, this rant should come as common sense to many here in TRP, but it's good to touch explicitly on the basics from time to time.
Have a great day!
