Closing Experiment !

So i went through my chats from a year ago or so and found out that i used to close with '' ....., when will we go on that romantic date ? ;)'' and who would have thought that it would rarely work, but i didn't know better. I wanted to test this close again with my current knowledge and skills so i collected 20 matches over the last month and closed 10 normally and the other 10 with '' ....., when will we go on that romantic date ? ;)'' to see how much difference it would make. In the ''normal close'' group i set up 6 dates so 6/10 in the '' ....., when will we go on that romantic date ? ;)'' group i set up 0 dates so 0/10 times, one chick just said: ,,idk''. ( i could have turned that around, but for this experiment i didn't) The results are just baffling, i did nothing different than the close and i got not one date set up in the second group. Why do you guys think that is ? is it because it sounds ''beta'' (the man not taking the lead) or because women are so indecisive and once they have to decide something they just lose interest ? I would really like your input on this, this really interests me. Your experiences with bad or weird closes are welcome as well of course.
