Just think of what might be made of your future King's earlier conduct (and I understand by his own admission!!).
There is a precedent there. An earlier long serving Prince of Wales put it about a great deal while waiting for his mother to vacate the throne, and all the while he was supposedly respectably married to the future Queen Alexandra. By all accounts as King Edward VII he was generally respected as a monarch.
Going off at a tangent, as a young Scots Guardsman my father was on parade for the funeral of Queen Alexandra. Quite a link to a bygone age.
