hai, i dunno what to advise u also... me got problem too.
Me and my bf dun shout at each other one, but being like this also
got problem... cos when one day you juz raise ur voice a little,
die... hai.. dunno how to explain... juz die lah...
best is dun tok on the fone when u wanna settle things, talk to
him/her face to face... so you can read her body language at the
same time... y body language, cos somehow u can tell if he/she is
lying, or keeping something to her/himself...
this is juz a suggestion...
all the best.
