whats the difference between love & infactuation?

1.              LOVE VERSUS LUST

• Love is complete acceptance,When we allow someone to be exactly as they are, without any belief that they aren’t good enough, without any belief that they would be “better” if they were different, this is love.Love is completely unconditional, Love has no conditions. When we truly love someone, we can’t stop loving them, regardless of what they do or say. If our love is dependent upon the other person acting and speaking how we want, then this love is completely conditional. We often confuse this to be love, but this is just positive thoughts about someone. This is just loving what a person says or does, not lovingthem.
•  Positive thoughts or the thought “I love you” isn’t necessary to love. Sometimes it even gets in the way.Love is selfless: True love doesn’t want anything in return, because there is nothing it needs. We just love for the sake of love. When we love someone, we don’t look for them to fill our needs, love us back, and all those types of things. If that is what we are looking for, then we are just using the other person.  Love is completely selfless.

• Lust is a product of physical attraction. It corresponds to sex and outer appearance. True love encompasses the whole of a person. Even when your partner gains weight, goes gray or becomes poor as a pauper, your love doesn't dry up. Love often deepens with time, rather than dissipates.

• Infatuation is a nonsensical and typically short-term emotional high that causes a person to obsess about someone else. Left unchecked, it can lead to the unhealthy -- and even criminal -- act of stalking. Emotional surges are great but they are just that -- peaks that aren't sustainable and are, at their worst, one-sided. True love is mutual and lasting. Both sides of the relationship should be equally love-struck for it to blossom.

• Scientists believe that love is embedded in the mind rather than the heart. Love activates the release ofdopamine, a neurotransmitter in the brain that makes you feel elated. According to neuroscientist Thomas Insel at Emory University, monogamous love triggers the same brain circuits as drug addictions to cocaine and heroin 
• In fact, we're genetically inclined to choose a lover based on that ever-important first kiss. It's called themajor histocompatibility complex (MHC), and it's a sequence of genes tied to our immune systems. Men release MHC in their saliva, and women choose men with a different MHC makeup than their own because less genetic overlap produces healthier children [source: Minnesota Public Radio]. So being stuck with Cupid's arrow may be as much scientific as it is mythological.
• Even the coldest of souls fall in love. Once bitten, whether it's a product of compatible MHC or the release of dopamine, the side effects are undeniable.
