I'm not going to write this because I'm uncomfortable hearing, seeing, reading, thinking, and (most likely) writing cheating plots but have this Jaskier/Geralt hurt/no comfort idea I thought of
Probably to definitely ooc but before meeting Yennefer, Geralt and Jaskier had become a couple. Geralt presented Jaskier with a ring with a wolf head surrounded by green gems. It was an engagement ring, they're engaged.
When they meet Yennefer Geralt has sex with her and Jaskier believes (and prays and hopes) that Yennefer just did something to him and it's her fault. Geralt wouldn't do that in his right state of mind!
But then Geralt acts like they did when they first started traveling together. There's no more looks, no more hidden smiles, no kisses, no sex. Every lovely thing he used to do for and to Jaskier gone in a day. But that's fine! Jaskier still loves him, still continues to buy him his favorite things, defend him, etc to show him that he still loves him. He's still here, he still believes in him, he has hope.
And they keep meeting Yennefer. And they keep having sex. Jaskier lives in denial though. Because Geralt was the one to propose! There's no way he would cheat!
And then the mountain.
He goes to the coast, stands on top a seaside cliff, throws the engagement ring into the ocean, and sits and cries and thinks himself a moron.
And when he eventually returns to Oxenfurt he has to heartbrokenly tell the blacksmith that they can stop making and/or sell the engagement item he wanted to give to Geralt.
Chapter two or next installment: it's not even until Yennefer and Geralt get rid of the djinn's wish years later that he realizes he cheated on Jaskier. Remembers that they were engaged. He goes to Oxenfurt to apologize and hopes Jaskier will come back. He's a professor now. Geralt stands in his classroom doorway and shittyly apologizes. Jaskier doesn't look him in the eyes, just below, and says I don't forgive you, thank you for the shitty apology "but I don't ever want to see you again."
