>>>I don't know. We don't REALLY know that they were going to get married. Maybe Anna was fighting him on it and he had to act quickly to salvage some of it.>>>
Yes, it's only HIM that is saying that they were going to get married. And this was said AFTER she died.
Even though it murky's up the legal stuff--it may have been his best bet to have ANS dead to see what he could salvage after the fact if she was fighting him on everything. The murkiness makes it better for him if this was the case.
