All I can say is, given that she is your gf, and there love in
between, she would not go out with a male fren or go oversea with
him. As a gal, I must respect my bf who love me, not
trying to make thing bad for him, afterall, he is my dear one.
Going out in a group of frens is not really a problem, but I still
need to consult him, but going out with a single male fren is
definitely making things worst than good.
I believe that TS gf is not serious with him, and he is taken
for a ride by her.
This is the first time we have the same common opinion
