"Friend zone" means that she is not attracted into the guy. She might respect him, like him, find him pleasant and still not see him as potential romantic partner. She can even find him attractively looking and still not find him as a potential boyfriend. Some boys tend to think it is going to change if they do enough services or help her a lot of whatever. It does not work that way. If you need to work hard on her, then I do not see relationship looking out of it.

It does not mean friendship can not turn into relationship. It can and all my relationships were like that. I would not date somebody I did not knew. I have also seen couples that originally disliked each other and became attracted only after they knew each other. However, it never went to one-sided "he follows her and help her too much" friend zone.
