I don't know about that. None of us know what Steve has already done. Given the severity of his meltdowns, his aggresive nature, his views on violence towards women, and his opinions on discipline, I think it would be a minor miracle if he hasn't lashed out at least once.
There are many women who would be prepared to keep such a thing hidden, especially if they love the person, and truly believe it is the result of a medical condition.
