Is there a point in talking

Basically I rekindled with my “fwb” and when I saw him after two months during sex he said he liked another person and didn’t feel a connection between each other. So I ended things. He’s recently been messaging me and last night I was out and near his and he said I could crash at his and I was drunk and said no why would I. Anyway from the messages he apologised but is there a point in actually talking about what happened it’s not like it’s going to be anything more and I don’t want to do casual.
