I don't know how much there really is to say that hasn't been said already! Feferi hates Eridan and she's just as happy putting him out of her life. She's more focused on taking care of Sollux than trying to make amends with Eridan again. She tried it and had it thrown in her face, so she would prefer to spend her time with the people she loves and cares about-- which she has been doing a lot of lately! She mostly just doesn't think about him if she doesn't have to.
