I was reading your description and the first thing that came to my mind is Drunk in love and it seems you already read it. I feel like this is such a popular trope in a lot of bl manhuas.
Have you read ‘substitute relationship?

I like stories where uke is very in love with the douchebag seme at first until they realize the seme does not deserve their love. The uke then ends the relationship and is ready to move on. The seme would then sober up and realize how much important and irreplaceable the uke is in their life.
Stories like Drunk in Love and Sissy, would you know any stories that are similar?
Thank you in advance
