Infatuation is the initial, instant attraction and intense desire for a person of the opposite sex.
Love is a friendship that has caught fire. It takes root, develops and grows one day at a time. The process is slow.

Infatuation lacks confidence. When he/she is away you wonder if he/she is cheating you. Sometimes you check perhaps even discreetly.
Love means trust. You are calm, secure and unthreatened. Your beloved feels the same also and this makes both even more trustworthy.

Infatuation is marked by a feeling of insecurity. You are excited and eager, but not genuinely happy. There are nagging doubts, unanswered questions or some unclear actions about your beloveded that you would not like to examine too closely. It might spoil the dream.
Love is quiet understanding and mature acceptance of imperfection. It is real. It gives you strength and grows beyond you to bolster your beloved. You are warmed by his/her presence even when he/she is away. Miles of distance do not separate you. You want him/her nearer, but near or far, you know he/she is yours and you can wait.
