Well....

It seems that neither of you realized how strongly the other felt. And now you get to deal with it.

First, I'm wondering if there isn't something else here, and the little kitty was just the trigger? I know it seems trivial, but obviously it isn't to him.

Here's the thing, and Lisa touched on it. You backed him into a corner. Not on purpose, perhaps, but that's what happened. You asked, and he said no. Then you got the kitten anyway... so he is thinking, why did she ask, if she was going to do it anyway? Is she listening to me? To him, the issue is a lot more than the cat.

So, now you have to decide. Is the cat a "hill to die for"? I can't answer that for you, noone can.

I still wonder if there isn't something else... but then I am a cat person, so getting a kitty wouldn't bother me at all!
