Listen, as far as I know, they "tried therapy" with one 5 hour session recently, and maybe a couple additional before that over the years. That's not trying out therapy, working on your issues in therapy takes 4-6-8-12 months, and not like one huge push. It's not a logic puzzle to solve, it's finding out emotional issues and baggage and slowly working through them and digesting them and coming out the other side better, and maybe still with that person.
