Paul have his limits in communicating but it doesn't seem to me that they don't talk to each other. Then there are more times that Leora talks to Paul but we know that Leora is more "chatty" than Paul. This doesn't mean that Paul doesn't listen to her.
Anyway, in my opinion, the problem of these weeks is not Paul and it doesn't even seem to be something related to them. Leora, apart from not bating, doesn't seem to have changed her habits and even when she goes out alone it doesn't seem to bother Paul. It seems to me that Leora does nothing because of something she read here on CC. She had already behaved like this other times, although not for this long.
