Why Women Don't Date Friends?

I want to know why women refuse to date people who became friends first? I try this and all that end up are mive refusals from the women. I give up they say they want someone who behaves like me (respects them, is dependable, etc . . . etc . . .) yet they always say no and keep on returning to those douches they used to go out with and complain about their relationships. Frankly I am getting sick of this and one of my friends says it is only American women who do this so I am probably straight up going to swear off American women. I am sick of these parasitic "friendships" I have with women in which I give them everything they want I am done and if all women in the world act this way I am most likely going to shoot myself! EXPLAIN THIS BEHAVIOR!!!
