EDIT - ok so I just read some of the article you linked, I can't really fathom anything about that, I couldn't ever be in a relationship like the ones described so I guess I'm not qualified to comment on how to fix a relationship like that. My relationship is a partnership - not to say that we're equal in every way, we each excel in different areas and support each other as needed.
That said, I still don't think that advice is applicable to a lot of people, going from being a doormat to a arrogant alpha seems pretty extreme and likely to undermine the basis of whatever the relationship was founded on (assuming it was founded on something like her being a demanding princess and you being a cringing sycophant)
