Love does not automatically teach communication.
Two people can genuinely care about each other and still carry completely different ideas about conflict, affection, money, loyalty, privacy and apology.
Sometimes people are not only arguing about what happened today.
They are arguing with everything they learned before they met.
Understanding that does not excuse harmful behaviour.
It does explain why “but we love each other” cannot be the only relationship skill.
Love matters.
So does how people behave when love gets uncomfortable.
