Ok, opposites attract. But attraction does not say anything about the fit as a couple.
Me and my wife, we had been opposites, but on us was missing an elementary ingredient for a good relation: the respect.
She found in me a person that prefers to keep peace than to fight. Rather the opposite was she. So far the attraction.
When she started to bend me more and more, and started robbing of me more and more my weak personality, she didn´t realize that she didn´t respect me.
Opposites can live together as far as there is respect. A sado-maso couple can live perfectly together, but it is always necessary to respect each other.
