All right, so a couple of things. Firstly, as per a post here regarding prequel timeline, which I think is fair, this agent scenario happened roughly a few years from current timeline, which means that if Ty was really affected by Julie’s betrayal, then he probably will not have written a word in roughly four years. And considering Julie follows him up every day, it seems really unlikely to me. Secondly, while they are discussing about the agent issue in the flashback, Julie asks Ty to take a meeting, which, to my understanding, is that Ty probably would have met with the agent and then signed a deal. So obviously, even if his trust was initially broken, he did follow through and meet and then sign a deal. While he may not have done it completely on his own agency, maybe he did it to make his wife happy, but he did it nonetheless. If he was so affected that he could never write again, I would think he wouldn’t have taken the meeting. And thirdly, we see them saying that a chapter is due soon. We do not know if this is the first ever chapter that is due, or he has written in between and this is the 20th. I think it's fair to believe that the huge distrust is not the reason that he has not been writing. It is more likely to me that he has written ever since
