very sad for u boy, but it occurs in a lot of couples, not only u.
you will not know what she is thinking about. alot of times, what
we say is not what we think.
but i want to comment on something, if
she can get a stead after breaking up wif u in just 2 days, most
likely there are 2 possibilities:
1) to her, going stead is not a process in which she really needs
to like the guy, but can be just "tryout", so when she was wif u,
she may be just "trying out" too, and not seriously in love wif
u
2) she already likes another guy even when she is wif
u.
so sorry to say these cruel words, i'm also
a newbie here, but it all depends on u too, do not just treat her
words so seriously, she may not realise what she is saying after
all. gals & guys are both like tat. Anyway, do get on with ur
life, but do tell her that u will promise to be a better man/bf. If
she comes back, she will be happier, and u too. If she doesn't, you
have also changed to become a better man, and u should be happy cos
more gals will like u, and u will not regret, but she may regret
instead.
Stay happy each day, its true tat some one commented earlier,
whatever is urs, its just a period of possession, it will not last
forever. As we will be gone someday, so why be so tough on yourself
and ur soul to struggle for something which may not even
last?
Sorry if i offend or hurt any of u, just hope to help. You can also
add mi in msn or icq so that we can chat, in case you feel sad,
frens will always be there to lend a helping hand.
