grounded

..now, i'm feeling so blue. so woozy. so grievous.i'm grounded with hang-dog feeling...

there's a girl who loves a boy.
their relationship started around 1 year ago.
they have a lot of altered characteristic.
the boy is a cool person, childish, very bad negative thinking , 100% loves his girl , jealous person , romantic , too realistic person.
nonetheless, the girl is very funny and talkative girl , careless , a "day-dreaming" type person , not 100% loves her boy , can't be so expressive.
this couple is going through a long distance relationship now.
sometimes this couple can be so happy.. but in the other hand, this couple can be extremely damage of feeling.
the boy : "i love u so much my girl"
the girl : "yes.i know"
the boy : "only that??"
the girl : "of course. what else?? what would u expect from my answer?"
the boy : "hmmm, at least u reply the same sentence to me."
the girl : "oh, okay, i love u so much my boy."
the boy : " oh..my.. GOD.. nevermind"

will this kind of relationship last forever??
