I used to be the kind of "nice guy" that you are referring to, and still am to a degree. What has changed is that I no longer accept new "female friends" in my life, I've had enough of that in the past to last me a lifetime. If I meet a girl and I like her, I let her know. If she doesn't respond, I accept it in a polite joking manner and never speak to her again. If she for some reason insists and wants to hang out even though she rejected me (as they often do, girls love to surround themselves with guys that like them), I openly let her know that I don't want to see her anymore and wish her the best of luck. It has helped me maintain only the friendships that matter, the real ones, and protected me from inevitably getting hurt and feeling terrible, as was the case every single time I got friendzoned in the past.
So...basically, it's not worth putting time and effort into friendship with a girl if she's not eventually going to sleep with you?
Wow. Well, at least you're honest.
It's funny how many of these "nice guys" seem to think that being nice isn't just a mark of a civilised human being, but that it requires some sort of pay-off. And how often they don't respect the girl enough to consider her friendship worth their investment. I mean, I've had friends I've fancied, and yeah, it's disappointing if you can't take it to the next level, but I still wouldn't give up the time we've spent, the fun we've had, or our shared interests.
Because an actual friend should be more than a potential date (for either gender). If they're not, you can't honestly be surprised they saw through you and dumped you like a hot potato.
