Rygar, you're so right. You made the connection "nice" = "wuss". SO not the case! They are too different words, yet thats what guys that we refer to as nice guys really are. A strong woman can't respect that guy, as much as she may like him, which is why he ends up being the "friend" type only.
HERB-GAL LISTEN TO THIS: one thing about "nice guys" with no backbone is that they often cannot stand up and confront you when there is a big problem, or when they need to break up. You can be left hanging for a long time or have a long painful relationship because they don't have the ability to confront issues... should you be so unfortunate to actually fall for someone who is too "nice" to do this.
But you see, this is not niceness or kindness... this is cowardice. To not confront someone instead let them suffer is not kind to that person. For example, instead of breaking up, leading someone one while something is wrong, then eventually being more and more distant until that person, confused and hurt, does the breaking up... that's the type of thing a "nice guy" wouldn't do because they can't bear to hurt you directly. But it is not nice because they would then hurt you far more and far longer than just a direct break up.
This is just one example of why a nice guy who is really a wuss is not nice at all, just a non-confrontational coward. I'm with Rygar - a man who can face things is a better fit for a strong woman, and if they are also of high morals, they may be nice in a way that counts.
