Um, how about being direct and telling him you are in a bad mood?
I agree with OT. Clearly communicate what's going on to your H so he can't build a story about how it's all about him, and then he won't keep poking you so that you get more cranky.
How about,
"I'm sorry, H, but for some reason I am just in a foul mood. I'm not sure why (or, I'm really stressed about a project I'm working on...I haven't been sleeping enough, etc.), but I know it'll work itself out soon enough. Sorry to be such a crabby patty."
Yes, you have the "right" to be in a bad mood around H, but you do have to make sure you don't turn that mood outward or get snippy with him when you are. Just be honest with your H, and I'll bet he'll want to be supportive. And if what you need is just some quiet time to get it together, ask for it. Tell him your whole body is leaking skulls and crossbones and you want some time to kind of let it all go.
He's just concerned and afraid...he knows he's behaved badly...and so he worries too. So just be clear, okay?
Have a great day! Are y'all getting as much rain up there as we are down here?
