It's the same reason why Haney stepped down gracefully, and why Ronnie is melting away---ego.
Haney had a family, was grounded. All Ronnie has is lifting weight, bodybuilding.
I may have given Alti sone ish, but I think she was too young for him...he was already stuck in his ways. He needed some gumbo making 40 yr old to keep him in his place.
