I’m a female member. There’s a man I’m close to whom I see regularly about twice a month.

Maezawa from the Corporate Planning Office here as well. Every now and then, there are cases where the man’s wife finds out about everything… When that happens, he usually can’t be contacted for a while. And if he resumes his activities afterward, he’ll often change his phone, so the LINE account he used before may no longer be available. There could also be various other reasons, such as getting into an accident or suddenly dropping his phone in water. I don’t know what the situation is this time, but it might be worth sending a neutral message that’s easy for him to reply to, just to see what happens. You’ll be able to tell whether it gets marked as read. If you still can’t reach him for several months, you could contact the club staff and say something like: “I’ve lost contact with the man I went on a date with before. Could you ask him whether he’s been in an accident? You may give him my contact information.” They may be able to check with him. If you still don’t hear back after that, I would assume he may have moved on to another woman.

I’m Bouken Shonin, a columnist. There could be various explanations, but I suspect the man you were seeing is simply popular with women. And because he’s popular, there’s also a good chance he became interested in someone else. Among male members, there are surely many charming gentlemen who can naturally win women over without involving money at all. For men like that, joining a dating club comes with the added benefit of being paid—so if they’re popular, they may be able to date almost any woman they set their sights on. That said, a man’s time and money are limited. As a result, he’ll naturally start ranking the women he’s seeing. If someone falls below a certain threshold, he may simply stop contacting her. As another respondent suggested, rather than sending anything heavy, I think it would be best to casually message something like, “How have you been? I’d love to see you again.”

I’m だて◎ゆめ, a male member. > She suddenly stopped coming altogether. A lot of things can happen in life. I’ll answer based on what I would do. There’s a good chance something happened that makes it impossible for her to send a message, even though she wants to. She may have collapsed and hit her head, be in the ICU, or even have passed away… I don’t know how long it’s been since you stopped receiving LINE messages, though. It might be a good idea to send a message checking whether she’s okay. After that, if there’s still no response for a while, I think it’s reasonable to assume it’s over. It’s also possible she found a great girl… though I think it’s unlikely that would be the only reason she stopped contacting you.

I’m Flagmaker, a column writer. Maybe there’s a reason he’s uncomfortable telling you. He might be short on money, or seeing another girl. As others have suggested, it’s probably best to start by casually checking that he’s okay.
