Things could have been much worse. I recall seeing girls who go
hysterical when they suspect their bf cheats on them, refuse to
talk to their bf, break up with them, start crying for several
days, sinks into depression, and eventually suicide(okay, so i
haven't actually SEEN this happen).
You're hurt, because she doesn't trust you. But maybe she has seen
too many signs of 'something' not going right in the
relationship.
If its me, i'm just glad that my gf accepts what the girl says...
else i would be having much more toruble in this relationship. I
will be glad this is over, and hope to push this relationship to a
more understanding one on both sides, more communication, so that
she'll ask me straight what happened if she's doubtful, instead of
shelling herself.
Sometimes we forget, that When we love
someone, we give them the power to hurt us. So how are you
using this power your girlfriend has given you?
