Yet another "This is my personal experience, and of course it reflects the whole world!" subjective rant, expressed as an universal rule. There is a term when someone think s/he is the center of the universe and everybody is just like him/her: solipsism.
In reality, we're all different: women choose partners because of different qualities and reject men for many different reasons (and men do the same).
"The real reason not a single woman wants you"... might be lots of things: sometimes it's about the looks, sometimes it's about the money/status (for women), sometimes it's about the personality; sometimes it's about all three.
Telling the whole world "Things works THIS way and this way ONLY" is a pinnacle of egotism - and ignorance.
