Oddly enough, I'd argue that time and distance has actually done Julexis... well? Lemme explain, I was never a fan of the ship when it first started up in 2013 (I didn't like Julian dragging Alexis down with the mob stuff), though I did see why they garnered such a sizable following (the actors had chem) . After the emotional abuse and knife incident that Julian inflicted on Alexis, I was disgusted with his character, with Julexis, and with the idea of them ever getting back together - and plus, what kind of example would that have set for Kristina (an abuse survivor) if Alexis went back to Julian?
Then something changed. The writers went from making Julian dangerous, but misunderstood to completely evil (the emotional abuse/knife incident) to reforming him as the man we see on screen today. The thing is, I like the new Julian, I like that he's growing beyond the mob and that he's somewhat changed as a person. When they paired him with Kim, it was good exploration of Julian actually having a healthy non-mob-influenced relationship with a woman. At first, I thought Kim/Julian had no chem, but they worked on it. After a while, they were alright to me chem-wise, but I still never called myself shipping them. Now I think I like the chem between Alexis and the "new" Julian lately. It hit me out of nowhere honestly, even though I'm still not sure about that being a thing again.
