I was trying so damn hard to give him the benefit of the doubt because I liked him in the first book. But no more. He emotionally abused Feyre. But not only that, he emotionally AND physically abused Lucien. Instead of getting Feyre away when he had the chance in the first book, they had sex. Seriously? After that, he and Ianthe ruled her life. Something that also gave me red flags was during the wedding, he tried to pull her to him. To me, it kinda seemed like he was trying to force her to say yes when she started hesitating, but that's just the way I saw it. He acted like a complete and total baby when Amarantha hurt the girl he loved, at least Rhys fought for her, and offered his help. Lucien was being watched too, but he still at least came to try and help. Tamlin didn't yell a warning to Feyre when she was stuck with the worm. The thing I hate most was how badly he treated Lucien, and I'm not sorry for rambling about it. He treated Feyre bad too, but she got out wayyy sooner. Lucien was still trying to be his friend, and be nice, and Tamlin still treated him like trash. Also, he let Ianthe relentlessly come onto him. I'll leave the Ianthe thing at that, because if I don't, I'll go off into another rant.
For the few that read my rant, thank you.
