I haven't read the books. I find the Jimmy/Jenny storyline depressing too but realistic because some people do important things without being that bothered about them in the long run.
I know someone who broke up with his long-term girlfriend about a long-running dispute about the timing of their first child, or whether she wanted one at all.
He got another woman, who'd always fancied him, pregnant and then wanted to go back to the original woman when he found out. He couldn't really understand why that wasn't a goer.
He now has another child with the second woman and they appear happy. I'm still friends with him and his ex who doesn't have children and probably never will. Who knows? I don't live in their pockets.
I am the consummate diplomat.
I like him very much but I find him very chilling in his pragmatism. It's buried in his childhood, I think, and I'm not going there.
Anyway, who could predict that a stupid Sunday night women's programme could be so deep? 
Oh and btw hackmum, I don't know how many people want to see the return of Chummy, but you're up against me and my mum
