Try to ask a question in response or just rephrase what you've heard. It can feel awkward but the key is really taking a little time to think - advice I should take my own self.
My H did ask me a fair bit where I was with the whole thing and I held firm for a bit by wondering why it mattered to him, since he had made a decision to leave. Eventually I caved a bit by saying that I'd like him to stay here while he continues to work out whatever he's going through.
In my case, this has worked out sort of okay, as he seemed to really appreciate the reassurance. Still no commitment to stay, though, and this morning (after a couple of really nice days together), he kind of rubbed my shoulder when saying goodbye, rather than kissing me. I have told him that I am not initiating a lot of physical affection because I want to leave it in his court, not because I don't want to touch him. He tells me that for many years, he felt rejected and unattractive, so I'm walking a fine line between triggering bad feelings from the past and pushing things further than I should right now.
Asking questions isn't whining; neither is sharing your feelings about what's going on.
