Okay look the Tamlin from book 2 is not someone I support and I do not condone his actions BUT Tamlin from book 1 was a good man whose heart ached for even the enemies he killed. Sure he went through a lot at the end of ACOTAR but in the final scenes he did NOT change into this weird caricature of himself that actually sounds nothing like him save for his appearance, he was the same Tamlin but one with more hope and freedom. But this man saw the love of his life get tortured and then killed because of him, obviously he’s going to have issues! But issues like this require patience and communication which Feyre was terrible at. To be fair she was also going through PTSD but she could’ve said something after a few months when she was doing a lot better. Instead she turned bitter and cruel and used Tamlin’s unconditional love for her to break him down more. She used his broken mental state to justify her actions and felt no remorse, knowing full well what she was doing to him. He dared to hope again and she shattered all the remaining stability in his life. IDK about you but that was a total bitch move and I really hope Tamlin gets a mate ( one who deserves him) and that he gets to go back to being the person he was initially written as, even if slightly changed due to his experiences. Experiences shape people, but they don’t completely change a person into an unrecognisable different person! Let’s not do this simply for the sake of plot Maas.
