We often see on here and other places that mom should be "thankful" that SM treats their kids well. Really though should they need to be thankful? Shouldn't it be expected that a child's father chooses to be with someone that treats their kids well? I generally think that in spite of many pitfalls of stephood most stepparents do not go into a relationship intending to be mean to kids or cause futher chaos. Do bio parents really need to be thankful when chaos does not happen?
