This was my earlier approach when I was younger. And it was not very successful.In a very formal way. Sort of expaining to her why she would be the kind of girl I really like without specifically saying I liked her.
So it's indirect.
Me: "When it comes to girls I really like [certain qualities]. You have those qualities."
But then when they press for a difinitive answer I get really uncomfortable.
Her: "So you like me?"
Then I give some evading answers that all clearly imply yes, but it's so hard to directy say it before she confirms that she likes me too.
This was a later approach and was more successful.Maybe I'm an aberrant specimen, but I've always been pretty direct in this regard. I prefer to just take my chances and kiss her than to bashfully sit there, trying to think of the right thing to say.
I use to try to rationalize my feelings and explain them. I did this several times (explain my feelings) to one woman over many years and never made any progress with her. Many years later I went after her passionately when the opportunity came. I felt her melt in my arms. I wish that I had taken this approach years earlier with her.
