I know how to escape hellzone, err I mean friendzone. It is very simple.
If you are in the friendzone, she likes you, but not in that way. And if she does not like that you in that way she will never like you in that way unless you change completely. And if you do change she can't see it because she will never notice it. I think you can escape the friendzone by backing off and then coming back later as a new person. But I don't know if that theory would ever work. And honestly it is not worth it. Changing for a girl is never worth it.
