Not to be judgmental and too generalized, but, a lot of men do become kind of whiny when they're sick. It can be annoying. Irritating. And frustrating.
That said, just take a deep breath. Try to be more patient with your bf. I'm sure that he isn't trying to irritate you. He'll feel better soon, and hopefully, back off a little bit. If not, perhaps he's interested in actually living closer to one another for more regular contact. If that is the case, then you both can discuss whether or not you're both together on this subject.
Best wishes to you!
