As a general rule of thumb, infatuation is a feeling of emotion
while real love involves a commitment and devotion. It can also be
based on physical attraction; often you don't know much in-depth
about the person you so-called love. Thus, infatuation is mostly
biological.
Then, infatuation is basically selfish where real love is basically
selfless . Infatuation is usually more interested in satisfying
yourself and the "feeling" than it is in the other person.
Real love is primarily interested in the other person. It seeks to
give instead of get. Love unselfishly seeks the highest good for
the other person.
Lastly, infatuation is weakened by time and separation but not
love. However, this does not mean that there will be no pain in
separation. On the contrary, there is great pain, even to distress,
in separation if you are truly in love.
And the last golden rule, TIME will always tell you the
answer.
cheers.
