guys, if they still wanna make things work, they still hope for
a future with u.. then there's no reason they will say these kinda
things to u.
from wat i apprehend, he's hinting a break up, though he dun wan to
be the one to initiate..
like wat sgboy2004 said, the career thing could well be jus an
excuse. . something to justify for why he no longer had feelings
for u...
6 yrs is a long time, most gals see it as a part of a stable
relationship, yet for guys... it could be too stable?
and environment do changes a person, he might jus found something
worthy for him to commit himself to, and at the same time, realises
tat the relationship actually isn't his top priority..
if u really wanna try for the two of u, have a real peaceful talk
with him.. let him know wat u think, and your stand..
i think it could be tat both of u might have took for the long
relationship for a bit too much of a granted,
tat both of u forgotten how to be sweet to each other at
times?
anyway, wish u lots of luck.....
