You Can't Fall Out

I think it must be
a milestone in every girl’s life:
the first time she falls in love
with a married man.

Real love, I mean—
not the kind where you find out
and think, "Oh, well.
That was disconcerting."

I mean the kind
you can’t fall out of,
the kind that haunts you,
the kind that hurts.

Like all loves before it,
it is accompanied by pain,
overwhelming joy,
and, increasingly, fear.
