Why is it girls like to be friends first but then state that once you're in the friend zone, you have no chance of changing that? Is this another case of not knowing what you want?
Because it's not that cut and dry. There are friends first and friends only. This guy is asking about friends only.
Most of that is based on lack of attraction, or respect (or both).
Most start out as friends regardless.
If we find someone attractive we'd rather know there's more to someone than just that before we start looking at them as a romantic possibility - at least I do. So they remain friends until we figure out the rest.
If we don't find someone attractive (or find them attractive until something they say or do disqualifies them as a dating option) but they are still fun to hang out with, they become "just friends".
