Honestly, if I was your friend's bf, I would leave her,
regardless whether there is a 3rd party or not.
If I were to say, her possessive acts actually made the
situation worse. The way she act, the relationship was doomed to
fail from the start. If there is no level of faith in each other at
all, why bother having an intimate relationship?
cuz my friend's BF is considered as a good catch..
wealthy family, rich, yandao, gentleman & a good character
(i ain't sure if he is a putting up a front or what..but..on
those few occassions where we met up with her & her bf..this
guy is amicable & sociable..1 of those rare gentleman guy)
so can understand why my friend fear that he might get seduced
bah..so she keeps a tight control over her BF to ensure that ain't
"traps" to lure him.. =x
