It's human nature.. people take things for granted or rather
they just kinda FORGET. Especially during relationships, every
relationship has it's 'honeymoon'..I'm sure alot have heard about
it.. in the beginning, it burns with passion, it jingles with
laughter, everyone enjoys the honeymoon.. But usually it lasts for
only a while depending on well.. most of the time the guys, no
offence 
so most girls want the relationship to
forever remain like a honeymoon.. but for guys, it is really
impossible, maybe he finds it tiring, or useless.. it's all because
we think differently 
so as time past by.. less and less of sweet
talks, gifts, the care, the concern.. and then the accusation
comes:
"you are taking me for granted."
yah, you can't deny that the fact that you took her for granted.
cos you did, you neglected her.. and even though you can tell her
you still love her as much as before, she wun believe you, because
words aren't true enough.. actions speak more than a thousand i
love you.. 
so.. learn to not do that, if you
knoe you are not goin to be constant in giving her stuff.. dun give
it to her in a routine.. and occasional surprise will be better, in
case u run out of ideas 
learn to cherish, don neglect her.. treat her like how you would
have treat her like the first time you met her.. similarly for
girls too, don expect the guys to do everything, do something for
him too
