Theory of DNA about love..Is that true?

I once to read a post in internet. Its said what make us to falling in love is our DNA trying to find other pair DNA to make itself more goood or more perfect at the next generation. The feeling of love is our DNA trying to fool us, Instruct us to be in the " Breeding Session". It is a very importan part to incentive human to propagate. and its usually would find the people who have the most dissimilar DNA with u in ur living circle. usually with coordinate with our brain, it would automatic find out the most suitable people and incentive some thing to make us fall in love with that 'Target".of course, it would automatically exlude some target, like got gf/bf ,impossibility, less chance, etc. (excluding for some special case).

and when a old possible target is out of or living circle, or become impossible. or dead, or something like that. Our DNA would find another target after a period of time. although, it is not necessary that we had only one target at a time, i mean it can make us feel the "feeling" in many target, but with usually one of them have the most impression..or more deeply feel Why it would make us have the feeling in many target some time?to amplify our chance to success propagate mah . for example ,Mostly would have two "target" most impresive us in our life,one is recently "target" one is second "target". how to find which is recent "target" and whcih is second "target"? the recent "target' is, the one who u waiting or wishing he /she call u, thinking of he/she when u free or when u read some kind of love story or after watching a love movie, and would smile in heart while thinking. and would thining of he/she when read this post. and the second "target' could be ur ex-target, or impossible to c hase de "target' or got gf/bf "target'. or ur ex bf/gf. or someone u thining before sleep at some nite exlude for ur recent 'target'. why ?why two? dont ask me. the post i read din define it.

of course that 'feeling' doesn't really make u love one people at all. but encourage u to love to. feed good to someone, feeling 'special" to someone or something like that. but it is usually what or why the love start.

what i really wondering is.. if this theory is right.. then mine DNA must be falling in sleep or bluring like me in recently year. doesn't really have the "feeling' in recently year.. Is that my DNA spoil or this thoery is just some kind of bull shit????
