@AlexA I think you are a bit naive here :) Jealousy is a very normal thing for every human being and has nothing to do with religion. Some are more jealous, some less and i doubt that you as child are aware if your father has these feelings or not except if he showed them prior. I do now know your father, but i am just saying that it might be less about teaching you but about being uncomfortable with another man being in the house with your mom when he possibly is not :D — MansNotHot 36 secs ago

For option number 1, I think "I'm not available" would be an alternative phrase that could work really well, then leave it at that. It heavily implies you're in a relationship, but is not a lie if you're not. It certainly signals that you're not looking. — Belle-Sophie 32 secs ago

I agree with giving Sarah the opportunity to tell Bobby herself, but I think the way your suggestion is currently worded is more of a threat than a gentle suggestion and may encourage Sarah to react poorly. My suggestion would be to instead say something more along the lines of "I think it'd be best if he heard it from you instead of me, so I wanted to give you time to talk to him about it yourself before I see him next" vs "I am going to tell him, you have X amount of time until then". — Jess K. 12 secs ago

why was this downvoted? — WendyG 1 min ago

-1 Because: 1. This doesn't answer the question. 2. "Blackmail" is definitely not the right term". 3. You're attempting to justify the cheating with some really terrible reasons "What if Bobby doesn't make Sarah feel good"? 4. You don't take into consideration that the OP said they were good friend with both Bobby and Sarah, this answer really comes down hard on being Sarah's friend more than Bobby's. 5. It ignores the idea that Bobby ever finding out you knew and did nothing could also cause the loss of a friend in Bobby. — Philbo 1 min ago

OP has indicated that this is a potential safety issue, so getting the police involved is the correct thing to do if the behavior persists. — David Thornley 42 secs ago

Moving to another apartment is an undesirable solution. OP presumably likes the apartment, and it's always stressful and somewhat expensive to move, even if OP can find a similarly desirable apartment. It's worth putting in some work to avoid that. — David Thornley 21 secs ago

You can buy a low end power washer for $60; most consumer grade ones are at most a few hundred dollars. I don't know what kind of washer the big-box stores will rent for $60, but it's not necessarily comparable, and even it is, that doesn't make the price reasonable. — stannius 1 min ago

Upvoted because the downvote was totally wrong. This is a great answer, just like mine. It's a mistake, let it go... — Johns-305 22 secs ago

The downvote wasn’t mine, but your use of “other Americans” suggests that you are talking about the culture of Japanese in America - or at least, that the Japanese you’re referring to are also American. The question asks about Japan, and I’d expect that most Japanese in Japan aren’t American. — Lawrence 1 min ago

What you need isn't so much interpersonal advice as for you to change. Have you considered some sort of therapy? — David Thornley 16 secs ago

And I'm telling you (and others) why I think it is bad advice. If you want to ignore the "cheese" and let things be that is fine. If you want to do something to prevent this from happening in the future then tell her the truth. — Warlord 099 15 secs ago

On the other hand, she could have told anyone who was not Bobby's friend her secret, but she chose you. — swbarnes2 16 secs ago

I have no idea why he’s like this. If I were to be a father and I were to have 2 beautiful children, I would allow a male or a female doesn’t matter tutor to teach my children. — Alex A 44 secs ago

-1 Sarah is implicitly requesting that you withhold harmful information from Bobby. That is not a reasonable request. This answer does not provide sufficient justification to prioritizes being a good secret keeper for Sarah over being a good friend to Bobby. — eclipz905 1 min ago

Not an answer, but a note: People rarely cheat because their relationship is going poorly, or because they are tired of their partner. In many cases, they don't even know why they cheat. Your friend is probably struggling to understand this herself, which is probably why she could only say anything while drunk. — AlbeyAmakiir 56 secs ago
