works a lot just like me, so that will be a nice built-in manner of keeping things slowed down.
"Workaholic"? It's also a way to have a lot of space and distance built into a relationship. That's where you need to tread carefully; that could be an indication that she (or you) may be uncomfortable if the relationship starts to get "serious" for her, or for you. Keep in mind that a necessary component for a happy, healthy relationship is that of spending a good amount of time together. When that time together gets bumped by work needs, that can impair the relationship. Unless she's commitment phobic, in which case, that distance keeps her happy.
