Where did you get that family responsibilities comes before learning?
I like your question. Are you asking rhetorically, or are you really unsure of the answer?
Tums: Unsure
You’re giving me indigestion with your questions!
Seriously, it is (as all Jewish things are) a Machlokes. See Rashi & Tos. Keddushin 29B, Gittin 6B. I also remember a Gemorah regarding an Amorah abandoning his family to learn, but can’t remember where it is (probably somehwere in Kesubos).
