Their relationship is indeed toxic but TJ and Ian were each other missing puzzle piece, they can't be complete without each other. They have struggles, life together and history that Jo can't fulfill. YES, Ian said that he wants their feeling to last forever or keep it forever but they can't. WHY? because even when he's with Ian, he can't forget TJ, whatever he did with Jo he's low-key hoping he's doing it with TJ. They love each other from the beginning but they can't clarify it from the start. BUT now, they're doing it, living their best life together.
