Being in love is divided in three phrase.
1. Is when you are out looking. (which is not that important)
2. Is when two person find themselves attracted to each other. This happen mostly because of the smell from which the woman is able to detect the genes from the man and decide if he would be able to provide the perfect mix of genes for a possible child. ( Im not sure if its the same thing happens for the man, but i don't think so.) when a person gets the feeling of being in love it's actually only because of the release of dopamine, serotonin and norephedrine. These chemicals will however automatically stop after some time and then be replaced by vasopressin ( i don't know why this hormone should have effect on love since it is mostly effecting our kidneys) and oxytocin
3. I have just described is closely connected to sex because it's just after sex that the last hormones are released in huge amoúnt and gives the person a feeling of being connected to each other. However, you can still get the hormones just by being close together in the time of being in love and even after that.
