Hello.

Since you’re talking about a man from a dating club, let’s think of it in terms of papa-katsu (compensated dating in Japan). If it’s a monthly arrangement, then there can be a cancellation. If it’s pay-per-meeting, then either you meet and receive your allowance, or you don’t meet and therefore don’t receive anything. That’s all there is to it. Since it isn’t a romantic relationship, I don’t think there’s really a breakup. He simply isn’t meeting you, so there’s no opportunity for you to provide the agreed-upon service, and no allowance is generated. In other words, his need for the service being offered has simply decreased, including the fact that you’ve become a lower priority. With papa-katsu, the man may not have a clear-cut “breakup” either. He may prioritize another woman because she’s a better fit, or prioritize work and his personal life because he’s busy. If you become a higher priority again over time, he may reach out to you. There’s no benefit to the man in formally cutting ties with you. In my case, when someone becomes a lower priority, I put off replying to their messages as well. If I’ve decided I’ll never meet them again and even messaging feels like a hassle, I might cut ties completely. If you’re still connected on LINE, why not ask him directly?
