Infatuation.
All-encompassing, gut-wrenching, soul-draining activity that only requires the
active involvement of one individual: the obsessor. A second individual is required
for the peripheral need of providing the obsessor with an object of needless,
unappreciated, possibly unwanted, often unwarranted affection. The second
invididual may or may not be aware of his peripheral involvement, and may or
may not be willing to be peripherally involved: the object's awareness and/or
willingness of being an object of desire is of no consequence to the obsessor.

Love.
The most spectacular,indescribable, deep euphoric feeling for someone.
Love is an incredibly powerful word. When you're in love, you always want to be
together, and when you're not, you're thinking about being together because you
need that person and without them your life is incomplete.
This love is unconditional affection with no limits or conditions: completely loving
someone. It's when you trust the other with your life and when you would do
anything for each other. When you love someone you want nothing more than for
them to be truly happy no matter what it takes because that's how much you care
about them and because their needs come before your own. You hide nothing of
yourself and can tell the other anything because you know they accept you just
the way you are and vice versa.
It's when they're the last thing you think about before you go to sleep and when
they're the first thing you think of when you wake up, the feeling that warms your
heart and leaves you overcome by a feeling of serenity. Love involves wanting to
show your affection and/or devotion to each other. It's the smile on your face you
get when you're thinking about them and miss them.
Love can make you do anything and sacrifice for what will be better in the end.
Love is intense, and passionate. Everything seems brighter, happier and more
wonderful when you're in love. If you find it, don't let it go.

Infatuation is liking everything about a person, and seeing them as perfect.
You do not see their flaws, just overlook them and act like they are perfect.
Not to be confused as love in which you see their flaws, and just accept them.
