Love hormone

Love hormone is said to be valid only for three years however one loves one's partner,according to the medical research.On the other hand,envious feeling against one's unrealized love doesn't faded away by the time passes. because having such feeling is believed to be human's defensive instinct to be prepared for another negative case.I think the God didn't create us human being properly when we look at these two opposite cases objectively.

In my private case,I admit that my love hormone for my wife seem a little faded but our relation must have shifted to more psychologically dependent relationon.On the other hand,my envious feeling toward a woman who rejected my proposal long time ago seems dwindled after I became happy having my wife.
