We don’t know that for sure. Dick
Nixon and wife had strange relationship.
I don’t think you can judge things by a marital relationship.
Hoover knew that the Kennedy brothers were sharing MM, and was disgusted by it. Not to mention the two secretaries in the white house office pool that JFK would
relax with in the downstaris pool while Jackie was gone...
Yes, Nixon’s chief complaint about
his marriage was that he could never
get it down pat.
