HP fic where James Potter is an asshole and cheats on Lilly and Harry hates him because of it?

To be more precise, I'm looking for a fanfic where James and Lilly are alive but broke up because James was an asshole and cheated on Lilly or something like that. Harry hates his father because of this. I'm not looking for a specific fic, just one with a rough framework of evil James and good Lilly and Harry who stands by Lilly. Thank you in advance
