Do women involved in papa-katsu (compensated dating in Japan) keep it secret from their boyfriends?

There’s a man I met at a drinking party last year. Afterward, he asked for my contact information and invited me out to dinner, so I went. At the time, I didn’t have any particular feelings for him, so I told him that I was doing papa-katsu (compensated dating in Japan). After that, we became intimate. We never said anything about officially dating, but we continued seeing each other regularly. We told each other that we liked one another. Eventually, he told me that he had met up with his ex-girlfriend. Even though we weren’t officially dating, I liked him, so I got jealous. He said he wouldn’t see her again, but sometimes he wouldn’t reply to my LINE messages, especially on weekend nights. So I assumed he was seeing someone—whether it was his ex or someone else, I didn’t know. I started wondering what I meant to him, especially since I was doing papa-katsu. Even when I asked him, “You’re seeing someone else, aren’t you?” he tried to hide it. Was he hiding it because he didn’t want to lose a convenient woman? Or was it because he knew I would get jealous? I was suffering from jealousy and ended up telling him that I wouldn’t see him anymore. He just casually said, “If you want to see me again, you can,” which felt very offhand. I know it may sound strange coming from someone who does papa-katsu, but things between us are over now. Was ending it the right thing to do?
