Women will only stay committed for as long as a man is meeting their fleeting emotional whims and financial needs. Men will stay committed as long as woman is submissive and meeting his sexual and domestic needs.
Personally I say fuck off to "friendship" and all relationships - they're superficial at best. I spend most of my days alone with my thoughts and I wouldn't have it any other way. I expect and want nothing from no one nor does anyone of me unless I'm to be paid for a work product.
