“Exactly. Should have included it on the list as well. Thanks.”
You are welcome, but it seems to me that the gemara I quoted in eiruvin is contradictory in spirit to the one you quoted in kesuvos. Perhaps the point is that one should (or is certainly allowed to) treat his family like raven….but not worse than a raven. I can quote it in english if that helps.

You see, while the gemara you quoted in kesuvos in pro-family-support at expense of everything else the one I quoted is certainly not. It is saying that the highest levels of Torah scholarship can only be found in someone who acts harsh towards his family by limiting his support of them and focusing instead on Torah scholarship.
