Scientists have studied the phenomenon that is infatuation in an attempt to define the mysteriousness and intensity often attached to it. Some scientists say love happens when the brain releases a certain hormone in particular situations to give a person some kind of high, which if instantly taken away or stopped would lead to withdrawal symptoms similar to a person who is addicted to drugs. Yes, it is that complicated and explanations have gone this far.
"Love at first sight", while linked with intense feelings, is not intimacy. The good thing about it is that it is pleasurable while it lasts and may lead to favourable side effects, like renewed energy or weight loss. It empowers you to seek greater intimacy and work toward honing your intimacy skills. And if you have been lucky to fall in love with a more or less appropriate partner it could be the beginning of a genuine relationship.
However, infatuation also has its own set of drawbacks. One is that love is blind. It places you in a situation that allows you to overlook or not notice (at all) the flaws in another person (not that you should always be looking for flaws). For a person who is infatuated, even the most mediocre works of art can be precious masterpieces and, as with relationships, this is often when the expectations soar a lot higher than what is real. People who are blinded by love experience a complete loss of emotional control and only hear what they want to hear and see what they to see, until eventually the smoke fades and they realize that things were too good to be true.
Another is that love at first sight is temporary and the way down is almost always extremely painful. The good things will eventually fade away and people's true colors begin to surface, so that when the relationship ends, both harbour a lot of pain, not only for the death of the relationship but also for the disappearance of a dream life.
Most people in this situation often start pointing fingers at the person who initiated the transformation and unmasking. Taking this in mind, if you want your relationship to avoid this kind of emotional beating, you must at the onset be willing to read just based on realistic expectations and goals. Though most people dream of falling in love, neediness is not a good route to a greater sense of intimacy. Leisurely beginnings can also be pleasurable, are actually safer, and can ultimately lead to periods of ecstasy that resemble the intensity and pleasure but are rooted in reality.
