True, he didn't want him specifically with Cuddy. But he seems actually concerned about Wilson. Perhaps he feels Wilson can handle any normal woman, but (and he jokes about this) Cuddy is too much for him. Also, since he knows Wilson marries a lot of people, he worries about this too (and he jokes about this as well)

Then the following episode he starts digging into Wilson's sex life with Bonnie. I tend to think that House, as typical, wants both of them ONLY for himself.
