I agree with feow, maomao... your gf is still young and in her
mindset, guys go on net with a sole purpose that is to meet gals...
and with that mindset, and knoing that you are meeting ppl
online...
well you knoW... 1 + 1 = 2
so take your time to get her used to the idea... ultimately it's
about trust... like you trust her to handle the situation with her
suiter (maybe it's wise to ask a bit abt that... cos while gals say
they want their bf to trust them to handle the situation, we often
would feel a tad bit insecure if our bf do not show the lightest
bit of jealousy..); she has to learn to trust you with your
"suitors" or friends...
afterall she has known you for a long long time, she should know
what kinda person you are better than anyone of us here... unless
you are not showing her your true feelings, or your frustrations,
etc.
in a way this is still a "new" relationship... try your best to
salvage it, to gain her trust... but if it means changing your
whole personality just to pacify her, My gut is, don't do it.
