I believe Shane split when he realized that the control of the company was going to HHH and Steph. He had been doing the Linda thing, running the business side. He might be running mom's campaigns, I don't know. He had a meeting w/ Dana White, and it was rumored he was going to be buying into UFC, but in the end, I think it was more Dana picking his brain about over seas TV deals.

The guy is in his 40's, has a family, and probably got sick of doing the same shit he's been doing since he was born.
