Why did my partner Google "How do I break up with my partner"?

I was on my partner's tablet, not snooping as he often let's me use it, and when I was googling something that started with "How" his previous searches came up with "How do I break up with my partner". Would a guy Google this because they actually want to break up? We're happy and he gives me no indication that he doesn't want to be with me, so I'm trying to understand the why so I know whether it's worth confronting him.
