But Ian isn't a toxic person? He's a man who has been hurt by the life and he wants to heal and move on
I think you need to read this again if you think that Ian isn’t a toxic person. If you think this all happened in real life, Ian just going between two persons is pretty toxic, all that unavailability, keeping secrets if not plainly lying, manipulating TJ in the past… I don’t even remember everything myself. Maybe he can change for better though. I even think that how jealous Jo was is a big red flag, even if he’s much healthier than the other two. TJ is in his own deeply toxic level though.
Only the toxic person can handle the another one. Jo can’t I want only TJ to end up with Ian. Cuz Ian always thinking abt TJ whenever he is with Jo.
