cause really theres a very small difference thats only visible through different circumstances and situations...
but basically they are both the increase of endorphins in your system brought on by increased level of dopamine, phenylethylamine & ocytocine.... so it's all the same thing untill you start to overthink, and consciously tell yourself you're in love; and thats simple infatuation untill the levels of phenylethylamine are mutual!... then you have sex, creating more oxytocine and then we have what's called "love"
Love is much better than lust: In the bible lust is described as sin. Love is true, lust is a lie. Love is inner and outer beauty, lust is sexual attraction. If we have love, why does lust exist? It is the work of the devil.
