Why does he joke about breaking up?

Anonymous
My boyfriend and I have been dating for 3 years now. Recently, he’s been joking about breaking up.
For example, he just asked me “are we getting a divorce?” I shook my head no, and he replied “damnit”
Whenever I ask him if he wants to be with me, he always says yes. Any ideas why he jokes about this? It’s not fucking funny.

He’s also looking to enlist in the Army. He asked me “if I broke up with you, would you take care of my dogs when I’m gone?”
Wtf?
