Seriously, D, I think you -- both of you -- are making amazing strides toward quietly twining your lives back together.
The cat thing, in particular, seemed huge. As you pointed out, it's a lot of upheaval to import a new animal into an already-menageried home. The fact that he didn't cavil at all is encouraging, IMHO.
My gut feeling (I'm full of them today; wink) is that it's best to just let it happen without feeling the need to discuss/call attention to it too much.
I don't mean asking his permission as you have been doing; I think that's a positive. I mean the suicidal impulse you *may* be feeling to *point out* how well everything is going ....
