I just really don't see why they couldn't have had them to stay together off screen i or even just not mention him at all.
She could still have talked about Joseph and that she'd come to realise she was wrong at that time if it was meant to be there to make elliot leave. Or, she could even have said that she was wrong at the time and she'd always love and miss Joseph, but she'd got a second chance with Jonny., thus encouraging elliot to feel that a second chance with Brigitte could work and wouldn't be a betrayal of Gina or her memory as he would always love and miss her too.
I also actually think that they over simplified her reasons for not going. It wasn't that she couldn't 'share' him with Harry as she was obviously prepared to when they reconciled on the day of Harry's birth. I think she could cope with that whilst they were in Holby. What she wasn't prepared to do was give up everything, her career, her friends, the life she knew when she wouldn't be 'first'. Also, she appreciated that Harry had to come first back then, she said so.
I don't think the relationship needed that validation now. We got it in his final episodes (especially their last scene) and even her reaction to his remarrying in 'Push the Button' and connie's episode last year. I don't think her love for him has ever been in doubt, even through her relationship with Jonny. It was just that she'd accepted she had to move on, and allowed herself to grow to love somebody else. Why couldn't it have been left like that?
Joseph has moved on as well. Letks not foget that he has married somebody else and was inept enough to send her an invite with no warning. If any dount as to the 'validity' or their 'true love' has come from anywhere, it is that and his actions.
So, it just comes across to me, that jac is the loser, once again. Joseph is allowed to move on and have a normal, happy marriage with somebody who we assume loves him and his child (probably more by now) but Jac isn't.
I still say that they could have kept them together off screen, with the mention of Joseph and idea that she loves both of them in different ways. And then, if by some miracle, Roberts wanted to return, they could have played out Jac not knowing what to do, not wanting to leave the 'stability' of her 'second choice/chance' and family life with the father of hef child but finding the pull of Joseph too strong to resist.
Unless they do actually have a return up their sleeves, i just didn't really see the point of breaking her and Jonny up, especially by the implication that nobody else is ever going to be good enough.
I do also wish they haDn't done it so flippantly and scornfully. For all Jonny's faults, he deserved better than that - if only because he is emma's father and generally a good one. You'd think elliot would have been more concerned too. I'd have preferred a quiet "we tried, but there was just too much water under the bridge and hurt done to each other to make it work but it's amicable". That could still come of course, but who to? Mo will probably be on the offensive for Jonny being hurt again (even if he is okay with it) and nobody else was invested enough in their relationship to care.
