You know why she will not tell you? This is
her psychological defense against reality; similar to the way
ostrich hides their head in the sand, thinking that its pursuer is
gone. Her mind is deluded by selective preception and to prevent
psychological reinforement to tell her otherwise, she speaks very
little about her relationship.
This trait also explains much about her inferior structure.
A good relationship flares with pride with you speaks about
them. Those that hush-hush are in fact the ones who have
dark problems that they never want to see through.
She is the perfect victim for such man. Unless she gain wisdom, she
will be a terrible victim of karmic love. Trust me, its more than
words - to warn her and you probably have your words flowing
in-and-out of her ears as quickly. You can try though, if you are
her good friend. But seriously, I seen too much of such case.
P.S: To desire for true love - the very first law depends on who
you chose as a partner. Under 9 Nine of Love - It is we, who choses
our partner, not the other way around. To chose a partner that
cannot bring us to greater heights spiritually, is destructive
relationship. 
Cheers
