Is ‘A Marriage Story’ the True Story of Noah Baumbach’s Divorce?

So did Noah cheat on his wife? It’s a matter of semantics and matter of whether or not you believe their assertion that it wasn’t the cause of the divorce. For the record, there is no record of Jennifer arguing that he had cheated. All the same, yes, it does appear that he technically had a relationship out of wedlock because, while they were separated at the time that he and Greta got together, they were not divorced yet. And some people still believe that there might be more to the cheating story.
