Coping

Realistic?

I read about yearnings for love
the love that will care,
will be tender and always be there
stay for ever
love that people will
make sacrifices for -
give it their all -
but there is always one to score
and then to leave
and one that can not believe
that it was over for good
that after she gave Love her all
it suddenly came to a surprising fall.
Are we realistic at all?
