In the UK, we're told that if someone let's us out, we should always look first to make sure nothing else is coming. Just because you allowed them to pull out doesn't mean you told them it was safe to do so, and they should have still looked to ensure it was safe to pull out. I agree with your wife and don't think you caused the accident. It was their fault for not being more aware of their surroundings.
