You will
gradually make your own sound judgement on what is the best for you
ultimately. This is self derived and not imparted knowledge or law
passed down from others because my cosmic lesson is definitely
different from yours, so the word 'particular' is not applicable in this
case.
You may feel that something may be wrong with you... easily
falling in love and wondering if what you are feeling is Love. To
me, such fleeting emotional moments may not justify the miracles of
Love, but of course, only time will let you understand eventually,
whether either one of the girls you fell for... would have an
everlasting impact in your life or not. (Although most of them will
probably turn out to be like anyone else).
Then, your initial cosmic lesson begins its course and you will
gradually form and shape your own definition of Love. Good or bad -
you will have some idealogy of love and probably apply them in the
future, and at the same time, constantly moulding, evolving and
changing them according to what your experience teaches you.

Cheers
