Yeah I agree with The Goq. It is difficult to believe that there were no familial problems and the person spontaneously decided to cut off ties.
I find it difficult to believe that someone without family problems would go off altogether. I’ve known a lot of boys that went off and ruboy k’kuloy did not get along with at least one parent.
And an intelligent reader has less of a reason to want to go off than anyone. There is more than ample sefarim to explain any question or doubts this person might have had. It is more than likely that there was a problem in the relationship.
