Right one Wrong one

It always happens that falling in love with someone who is consciously considered as a wrong person.
According to Paul Maclean's Triune Brain research, human brain has 3 distinct parts:

1. reptile brain - instinct reactions such as flight-or-flight, sex desire
2. mammal brain - it is the affection and emotion brain; governs social awareness and relationships--belonging, caring, empathy, compassion and group preservation.
3. human brain - rational brain. Logical resoning and highly intelligent brain which only highly evolved in human brain.

The social and love relationship in human world in complex. None successfully tested and got sound research result of this affair on human, like they done on other animals. Love involves sexual boundness, emotional belonging, and rationally desire. It is not as simple as rating the values of the 3 layers and add them up. The 3 layers interact and affect each other. Eg. fame, rich, reliable are rationally the symbols of a better mate, but the symbols reflects the ability to offer the basic disires of the basic reptile brain. ie. human brain helps the reptile brain to find a suitable mate. The same thing also happens to mammal brain. Consequently, the 3 brains think in their own way for other brains. It constitues the complex human LOVE.

Sometimes the human brain may consider someone is not a suitable mate, but the other 2 brains may think the same person as the right one. Thus, the conflict occurs in mind. Three brains insist their oppinion and make the brain owner confused about it. In most case, mammal brain wins over other two. It is because love bassically is just an emotion which is governed by mammal brain.

If the person situates in a poverty or dangerous environment, rational brain might win. If the rational brain lost in such situation, this person may have to pay the consequence even die. The cost is too high to let the mammal brain win.

Reptile brain only wins in one night stand situation. But reptile brain can easily convince mammal brain to think in the same way. Thist is the cause of love after a great sex. Although this person is rationally a bad mate.
