Am I stupid? I don’t really get why they don’t like each other anymore? I just kept reading and thought it would be explained more. Does protag like Aoi again? Was that what was implied earlier?

This is late as hell and you have probably figured it out but I think it's because they thought they made the other person hate them + they think they won't be friends anymore after the break-up which is true in some relationships.
I think that's how it is anyways.
