@Renesmee honestly It's not that easy, they are codependent and that's why it's so difficult for Ian to leave and for them to have a "normal" relationship, idk if they can work it out, but if they don't Ian has to either accept a life he hates or realize that Tj has changed and that he can't/won't give Ian the life he wants. It's kinda wrong towards Ian to chalk it up to "he can leave if he want's" cuz it's a complex situation. Also Ian has no identity outside of Tj and also has self sabotaging behaviour which is very sad.
