Why did the astronaut break up with his girlfriend?

He needed more space!
This is the classic space/personal-space pun — astronauts literally go to space for their job, so 'needing more space' is both a relationship need and a professional calling. The joke works because the excuse is completely plausible for an astronaut and completely unacceptable as a breakup reason simultaneously.
Shrug as you deliver the punchline — the astronaut's reason is so obvious to them that they're a bit baffled by the girlfriend's confusion.
