from my knowledge, it is not as often that a girl will initiate a breakup with a guy after >2years of relationship. assume a relationship where they fondle around for long enuff (may or may not include sex), and the guy is also very loving and devoted.

i hypothesise that, for her to initiate break up, den she must hav turned slutty. nid to hav 2 men instead of 1. or go for hotter man. (heck cases of the guy being unfaithful and fking other ladies.) from a psychological point of view, there is strong partnership bonds formed in the brain, and certain chemical triggers which are accustomised to touch and sense and feel with the guy. if she leaves this guy for another guyno.2, she may not be able to fully recreate the sensations and euphoria.

another hypothesis is that, men may be marginally better off in such a breakup, cos i reckon easier to hav the euphoria of love. and for men, it's easier to heck the differences. for women, harder. that's wad i tink. but i hav not enuff psychological reasoning as well as knowledge to back this statement. so if u're feelin kind, u can type sth.
