Unknown. But for this, precise legal status doesn't matter, merely that they're in a serious relationship.

Presumably, they're the sort of people to whom Hunting appeals, and thus went into Beacon (presumably) fully expecting to make it their career, which entails maintaining combat fitness for a great length of time. Any relationship that develops would be entered with that in mind. A change in mindset to derail not one but two incipient careers and aspirations, when they have no experience whatsoever or any fallback plans is unlikely, I deem, when they could very well just wait to have kids.
