The concept of "opposites attract" is usually used in a lot of situations, but this comes from electromagnetism (the study of electric and magnetic phenomena).
We do know that if two given bodies have opposite charges (one has a negative charge and the other has a positive charge) the coulombic force between the bodies is attractive. From this, the "opposites attract" idea is born. (A similar thing happens with magnets)
There exists a romanticization of science, to the point that a lot of ideas that come from science are extrapolated to other fields. (for example, there are people that try to explain psychology with quantum mechanics, which is kinda absurd). This is why the idea of "opposites attract" is often used in other fields than electromagnetism, like in human relations and things like that.
So thinking critically about "opposites attract", we can see that the only support of this claim comes from electromagnetism, so extrapolating this to any other field would be a mistake.
