Oh my husband didn't want all of our things either. It started with one dog. I broke him down and he agreed. Then, of course, he loved it. Then we got another, despite his misgivings, and of course, he loved it. Then we got chickens, which he wasn't so sure about, and he loves them...or at least agrees they serve a useful purpose and were a good idea. And then I hit him with children. Evil laughter He didn't want those either, but surprise - he loves them!
Now we have 2 guinea pigs, 2 rats, and 2 rabbits as well (although one dog has passed away.) And he loves them. Well, truth be told he wants to eat the rabbits. But he hasn't, and that is what is important!
Moral of this story: Spouses have no idea what they will actually love, and sometimes just need a little push ;)
