Confused Bruce ..

Bruce Jenner clearly has a strange emotional attachment to his wedding ring.

A ponytailed Bruce stepped out for coffee Thursday afternoon in Calabasas ... and we couldn't help but notice he was wearing a wedding band.

His marriage to Kris is over and out -- they've already agreed on the money split. He has some sort of new relationship/friendship with Kris' best friend, and she's clearly moved on because she's full-on dating Corey Gamble.

Bruce is a complicated guy.I feel for him especially as a motivational speaker
