We only had dinner the first time, and since the second meeting, it’s been an adult relationship (intimate) at her request. We make plans for our next meeting and see each other about once every two weeks. I assume she doesn’t like having her time tied up. I only message her on LINE once or twice a week when I have something to talk about.

That’s not really a relationship… These days, now that people don’t call as much, LINE basically serves as the phone—and it’s even more convenient. You can send concise messages, reply briefly whenever you need to, and have longer back-and-forth conversations when necessary, just like on the phone. You can reply only when you have time, send photos, search things online while chatting, and even add text or corrections to photos before sending them back. I think it would be pretty boring not to enjoy that kind of communication.

Thank you for reaching out. I think it depends on the nature of your relationship. If it’s someone you’ve met several times, you could ask them the next time you meet whether they have any concerns about how often you respond.

Are you enjoying this arrangement? Are you dating a sex worker? Is it more like a delivery escort service—having sex, chatting a little, and then leaving? If you’re happy with it, there’s nothing wrong with that, but personally, I don’t think I’d like it. Don’t you want to go on trips together or try restaurants that are said to be really good? It seems like things would end quickly if you stopped messaging on LINE, so if you don’t mind, I think you should just keep doing it.

Don’t you think it depends on the woman and the relationship? Some women message me every day or several times a week, so I don’t think it’s the same for everyone. Personally, I don’t consider it a relationship if the woman finds that kind of contact bothersome, so I either ignore or turn down invitations from women who don’t send any kind of everyday message.

It depends on the person, but fundamentally, I think the etiquette of LINE is to convey only what needs to be said, as briefly as possible. Sending a stream of messages when there’s no real reason to do so is bad manners. At the very least, it’s fundamentally wrong to think someone is cold or heartless just because they won’t engage in casual LINE conversation. “ They contact you to confirm the plans the day before” sounds like a heartwarming thing to someone unfamiliar with the scene, but with people you meet through apps or Twitter, it means there are apparently so many cases where they suddenly stop responding, break the promise, and end the relationship. Some even maliciously string you along with small talk before canceling at the last minute. And apparently, the worst ones are pranksters who don’t show up at the agreed time at all—meaning they never intended to pay for the date in the first place. At Universe Club, setting aside the women, the men tend to be a pretty innocent bunch, so that sort of thing almost never happens. So keep in mind that when she contacts you to confirm the plans the day before, it can also be interpreted as, “This woman has been around the block.”
