But was it really? They mashed up, He moved to Adelaide, had a breakdown, Jamie wound up in care and legged it to Erinsborough after being bullied by older boys. Cue intervention by Stu, Harold and the Kennedys and they were able to reunite father and son.
That was extra sour as Paul Keane had substance abuse problems and was in and out of rehab (Documented, so not libellous, admin)
He did get a second go with Fiona and that fell through. Then the thing with Jane in 2020 after Nicolette basically dissected the relationship by pointing things out.
Basically, James after splitting with Chloe and having a lacklustre 30th (got a $10 in a card from her few months after she left), decided to cut his losses and move overseas and after some stuff with a birthday balloon, He and Juliet took off. I dunno if they stayed together or what though...
