Also, as it was stated twice before (once by Kristi and Jennifer H.), Michelle is equally fiesty and hot-tempered. She yells at him, provokes arguments, and gives as good as she gets. I am not saying I condone it but I feel that's what gives this relationship a very human element. Unlike other soap couples, Danny and Michelle bring out the best and worst in each other. And like it or not, there are relationships out there that take this kind of thing a lot further. I will give kudos to the writers for not being afraid to take this kind of risk with Manny.
I also attribute Danny and Michelle's actions (or should I say reactions) to each other as the embodiment of their intense passion for one another. They are "combustible" when together, but that is part of their allure and why I keep watching ... hoping to delve further still in their many complexities.
