yours also 5 yrs...i can understand ur feeling, its lik losing
something so precious to you....yet u cun do anything...
lik wat u say, te guy cal, ask u to keep quiet, seems very knn, lik
wear" green hat" lea.,
although i also hate to tel u this(i was also in tis situation
b4,which i consulted forumers here) but i somehow agree to wat some
other forumers say,leave her, cos lik tat already no point mah, get
wat i mean? she be wid u but mayb bed wid him, very KNN...u can
tahan mea...????
If u know her parents well, attack tat guy from her parents side,
posin tat guy,(which i did
)i say things lik, she always
come back so late, neighbours see liao where got nice, parents
worry bout her..always smell of beer...thinks tat can make her mom
heart melt,say u dun mind losing her but cannot let her continue
being lik tat, she wil hv no future,etc...u sure can do it..but
most important, must see how she think liao
Gd luck.but i personnely think, i rather u short pain den long
pain,cos if u r together wid her those farking thought wil
automatic come into ur brain...which will indirectly make u
possessive, den again she may leave you...some FEMALEs really "Na
Bay Pua Chee Bai"some only lah.... 
Go chiong more,know more ppls lah, i now also starting to get
over
my 5 yrs also ex....u will know there is so many other better
ladies in singapore, only u have not touch their heart,sure can be
more confident in yourself...
