understanding..

hmmm...
how to get started leh?
i heard a story from one of my friends
a girl named A and a guy named B
A likes B alot
they are a couple
but B finds out that
she's a little bossy..
maybe more
she is so demanding,
that B cant stand it...
B is not allowed to talk to other girls
even if B is tired at night, he must accompany A

finally B breaks up with A
but A still likes B, alot
they remain as friend
A demand B treat her like his gf
but B just treats her like a friend
now A is very disappointed,
cuz B does not give as much as commitment like she expected

from this story
i think,
A should be more understanding
so what do you think?
