here my experience...just my two cent but after working on a night club as a bouncer for 5 year i know a lot about women psychologie (i.e garbage).
"just friend" = you're not sexual attractive but you got money or something like this (she think you can be an acceptable father)so she want to stay in good term with you IF the "alpha male" she really want throw her, so your just a "plan B".
Being a "plan B" is a really hard job, she want everything, bla bla bla, she don't want to suck or being fucked in the ass, a normal guy will loose 20 years of life esperance at this game.
but for the alpha male she can drink mud with a dildo on her ass, gang bang, being beaten, working for him etc etc.
women always claim for "dignity and respect" but can do shit for "the alpha male".
that why i got trouble to respect them.
