I agree. Intense feelings need to be channeled positively to the advantage of the relationship. Going from "fuck you" to "fuck me" from so rapidly is not healthy in the long run, although it could reap short term rewards like goof make-up sex. Ultimately there has to be some consistency in terms of how both partners handle their emotions. For example, you could have a dude who loves his woman to death, but manifests his passion through physical abuse.
