I agree! There were so many missed opportunities to explore Wilson (and by extension the House/Wilson relationship). I still wonder how the show would have been if Shore had stuck to his original premise of just having House, Wilson and Foreman as the characters. There probably would have been more room to explore all three characters in depth.

I also hated that Shore didn't push the House/Wilson relationship further because it definitely was the defining relationship of the show. I remember an interview after "Don't Ever Change" aired, where an interviewer raised the possibility that House and Wilson could be more than friends (aka lovers) and Shore brushed it off by saying that they weren't going to explore that further. That pissed me off because obviously if Wilson had been a woman, you can bet that they would have explored that. I think David wasn't interested in that and I think that it's a shame because there shouldn't be a double standard when it comes to portraying same sex relationships as opposed to straight ones on tv. (And yes I think House is bisexual and I think that's what they were subtextually (sic) saying in "Don't Ever Change.")

In the end, I think Shore realized his mistake in not exploring the House/Wilson relationship and I call bullshit that he still says it was just a friendship. A friend (no matter how close) doesn't just give up his entire life and fake his death to be with his best friend for six months.
