I'm not Tina, but I think I can give you some answer why Nash might have become unlikable, and this is from a really huge Nash fan from the first day he appeared.
Stealing kisses in the hospital corridor, then desk sex at the Sun. The Nash and Jessica story has been mangled almost to death by this kind of event hopping with absolutely no reliance on established character traits. Jessica's contribution to the cheating on Antonio is completely out of character, even for Tess, who adored Nash and would never have cheated on him. And then Nash, who had been developing into a stand-up sort of guy, wouldn't be trying to boink another man's wife at every ridiculous opportunity. It's horrible writing. It's horrendous story-telling.
I'm hanging in there by the tiniest thread, but I've no emotional involvement in these characters any longer. It's a bad cartoon and it could have been a great story.
Yeah pretty much, I feel that Nash is too pushy, he wants Jess all the time. Even when she's at an injured little girl's bedside. He needs to back the hell off!
And Jess needs to control herself! But maybe she's half Tess now... And Tess has no reason to try to be faithful to Tonio.
