If love is a lot like cocaine, does that mean that love is not good in the long run? how come all these people in long term rel. are still healthy?

False premise: I am not certain which rap song has taught you to equate a short term high/thrill? with love, but you need more help,than I can offer in the 400 words allowed. Since married love allows people to become complete, have a trusted friend, and share intimate moments, the body and mind are nurtured with a non physical spirit that cannot be described in physical means alone.
