bumper sticker

I’m sure this is all too common a thing, but I today I saw a bumper sticker that made me feel weird in a way I’m not sure I can describe. The sticker was on a pick-up truck (ever the gendered “male” vehicle if there was one) and it said in large type: “I LOVE MY WIFE.”
Oh, OK, that’s nice. It immediately made me feel odd. Was this more like those stickers that say “I (heart) my X breed of dog” or maybe more like the ones that proclaim pride in the honor roll child?
Isn’t the assumption that one would love one’s spouse? It just struck me as a whole “wife as property” thing…of course I might be reading too much into it.
What do you think?
