BFF & BF/GF

Erm...wats da different between (Best Friend Forever) BFF & BF/GF ??
erm...i m still wondering..
most of my friends said dat bff is one step above bf/gf...
meaning dat, they are too close to one another than instead of bcoming bf/gf..
they bcome bff...erm..is this really true ??
as a summary...too fren fren d..den bcome bff..
but then hor..if we nvr get close and fren fren with our fren den..where da friendship where
can berkembang and hubungan where can rapat..
erm..i wonder how and why..
sometimes, all this matters make us confused on where we are standing..
either bff or gf/bf...
sometimes da way they treat u like their bf/gf but actually they only treat u as their bff..
erm..so its quite complicated..
as i know, many of my friends already being traped inside this matter..
erm...wat actually bff can do and donts ?
and wat actually a normal friend or gf/bf can do and don't which bff can't do ??
wow..ahaha..aku pun tak tahu..
hard to differentiate...
if u are caught under the category of bff..will u proceed to bf/gf relationship ??
ahaha..this is a hard question rite..
