Hear me out here Tamlin is a topic we all have thoughts or feelings about right?
Tamlin the tool, Tamlin the Tampon, etc... You'll probably get mad or say things but I kinda feel bad for him after I read A Court of Wings and Roses.
True he did lock her up in his manor and really never let her roam free and kept her in the Spring Court almost like his prisoner but when Rhys died and Feyre was begging the other High Lords to bring him back well they all offered their power to heal him INCLUDING Tamlin who tells Feyre on page 690,
" Tamlin stood there. Staring down at me. Those green eyes swimming with some emotion I couldn't place.
"Be happy Feyre," he said quietly.
And dropped that final kernel of light onto Rhysand.
He was willing to make Feyre happy even though she wasn't into him anymore
So thank you for listening to my ted talk
