Lust is the feeling that is often mistaken for love at first sight. Lust is an intense and sudden attraction to somebody you hardly know. It is mistaken for love because the attraction is so strong.
Lust can feel like love because the feelings of attraction are strong and all-consuming. The emotions stirred up by lust can feel very real but they are based on a fantasy. To love somebody you must know them well but many people fall in lust while they are still strangers. What people in lust fall for is a fantasy of what might be and reality can get lost in the excitement.
Overwhelmed by physical attraction people in lust can't keep their hands off of each other. They think about each other constantly and talk about one another all the time. Lust is a happy feeling brought on by passionate attraction. If you are inexperienced in matters of the heart it is very easy to mistake all that passion for love.
Lust differs from love like night differs from day. Lust happens in the early phase of a relationship when people don’t yet know each other. Lust is based on a fantasy, and the fantasy and reality don’t always mesh up. This is where lust runs out of steam.
Although physical attraction is definitely a key ingredient in any romantic relationship, love is more than just a physical longing. If a relationship is all about physical attraction it is based on lust. Really loving another person takes time and it can't be based on physical attraction alone.
