Like Poles Repel, Opposite Attracts

Do opposite really attracts? Was it momentarily or forever?
Men are from Mars and Women, from Venus.
Why do Men get attracted to Women and vice versa,
When they possess notions that are worlds apart?
Whether you are the Man or the Woman,
Showing love is always different.
I know Man who are so very rational with Woman so sentimental.
I see Woman who are so independent sticking around with a man who cherishes her every moment. It's never equal and the party who's more emotional will tend to lose out.
Though love is sacrificing, it takes both hands to clap.
It takes time for acceptance, understanding, tolerance and forgiveness.
Lacking just one, would create rocks.
It was the difference that attracted both, yet it may be the difference that split them up.
That explains the increase of homosexuals in this universe where Martians would go with Martians and Venusians would stick with Venusians.
But even then, some difference would evolve.
So the challenge would be to overcoming your differences.
But is it really true that like poles repel and opposite attracts?
Isn't it better to have a partner sharing the same perception of love?
