Women find men confusing because... well, they're not men, lol. The same could be said in reverse. How many times in my life I've found out (after the fact) a woman I was "hot" for but let it go because she never seemed interested... just to find out (after it was too late for one reason or another) she actually was.
So far as I've always thought, men were actually more simple than women, at least in that regard. If we're interested, we'll usually just say so, or at least try to make it obvious. Why do woman play the games they do and pretend like they're not interested if they actually are?
Seems we all send mixed signals in one form or another.... hard as it may be in the face of possible rejection, I would imagine blunt and honest conversation and communication would solve most problems for both sexes. Too bad our ego's prevent such a thing, lol.
