is other girls more important than ur own gf feelings?

is talking to other girls that important? why are they lying? if they feel other girls is nicer to talk with why don't they be single and go flirt with millions of other girls. no one will ever care. right? haih for guys. disappointed with what they're doing. they didn't even keep their promises and they expect us girls to keep it. why don't they just go take that girl as their girl. all and every girl who flirts with my darling is a bitch! haih. if the girls is that important why do they still want their gf? what's that for? for them to play with? for they to do anything? is every guy in this world like that? or will there be a guy that will listen to their gf and won't do it. help me!!!!! i hate this life. he said when go to college or university time i'll understand. he say to change me before i become his wife. so funny! why should i understand it? i know i don't like it. if working time he talk. i don't mind. that's of course have to. that's the only thing i can see that a guy that have a gf need to talk to other girls. not flirt with them. i don't know le what they really want. haih
