In this fanfiction, there could be a situation where Ash betrays May out of jealousy. Maybe May has achieved some great success with her Pokemon and Ash, feeling overshadowed, makes a deal with someone that goes against May's interests. On the other hand, May could betray Ash if she falls for the lies of a character who wants to use her to get to Ash. This character might make her believe that Ash has some dark secrets and that she should distance herself from him.
One possible scenario could be that Ash betrays May for a powerful Pokemon. Maybe he gets offered a super rare and strong Pokemon but has to cut ties with May to get it. Another could be that May betrays Ash because she is influenced by a rival trainer who convinces her that Ash is holding her back from reaching her true potential as a Pokemon trainer.
Well, in the fanfiction, it might be that Ash betrays May due to some misinformation. For example, if he hears false rumors about May working with an evil team. As for May betraying Ash, perhaps she discovers a new training method that goes against Ash's beliefs and decides to side with a group that promotes that method, thus betraying Ash in the process.
