I’ve been seeing my papa for several years, but from various things, I get the feeling he may be meeting other girls too.

Hmm… As cute as he may be, I feel like he might be a bit too much for papa-katsu (compensated dating in Japan). You should find yourself a serious boyfriend too and spread your feelings around a little.

Rather than saying you know he’s seeing other people, I think it would be better to bring it up by asking, “Are you seeing other women as well?” If he’s upfront about it, you can simply say, “I’m not sure I want to hear about that.” If he tries to feel you out instead, you could bring up the situation you described in your question. Ultimately, I think the important thing is whether you can put what’s bothering you on the table and discuss it openly. I don’t think games or strategies are really necessary. It’s not as though you want him to change the current arrangement, and he probably wants things to continue going well with you too. It comes down to communication skills. I’m sure everyone has their own way of doing things, but I think it’s better not to make things more complicated than they need to be. That way, you can work things out with straightforward communication—which, to me, is how ordinary people can live reasonably happily. Taro

I think your papa is trying to keep it hidden, so pretending not to notice can be a considerate thing to do. If you confront him about it, he may see you as too demanding, and depending on the papa, it could even lead to the relationship ending. At least, that’s the kind of person I am.

He sounds like a popular papa. But if he’s stayed with you for several years, you must have a lot going for you. As for effective lines: “I’d break up with you if you cheated on me.” — say it cutely. “And I’d know if you cheated on me.” — say it with a serious, almost gloomy expression. The key is “I’d know.” As if you have some mysterious ability to somehow know what he’s been up to. “I’ll cheat on you too if you cheat on me” doesn’t sound cute, so I don’t think that one works. I kept saying things like that, and before I knew it, the other girls had dropped out and he chose to stick with just me. He’s my current generous (well-paying) papa. That said, there’s no one-size-fits-all script. It’s probably best to tailor what you say to the papa’s personality and adjust it according to how invested he seems.
