Interesting.  No comment though about how seeing woman while married constitutes infidelity.  Or has she stopped seeing women since marriage?  If she stopped seeing women, she is not bisexual.  If having at least one encounter with a member of the same sex including childhood makes one bisexual, most people are probably bisexual.  It would seem to me (IMHO) that one only gets the title that describes current activity.  Of course that notion will be shot down by those who need to say that sexuality is intrinsic and unchangeable.  Whatever.
