Um I have a situation

putting "kill her" as an option just tells me how immaturely you're looking at the situation and how you're not thinking why she did this. you're thinking in the retrospect "why did my friend have to backstab me like that just because i tell her this doesn't mean she has to blab about it"

lemme put this in a point of view Ты can understand. it may not be a good view, but i feel the need to drill it in your head
you're the one who told her about this crush. Ты disclosed this information to her, and if Ты didn't want her to say anything, why didn't Ты tell that to her?"
now, i'm not saying Ты didn't. i don't know if Ты did. i'm also not saying that this is your fault. it is something to keep in mind though.

telling her crush she likes him will NOT SOLVE ANYTHING, AND WILL PROBABLY COST Ты A FRIEND. REVENGE, или PAYBACK OF ANY SORT WILL NOT HELP YOU. IT IS A CHILDISH RESORT. just, no.

ignoring the problem will not make it go away. it will still be there, and it will lurk in your mind for as long as possible. ignorance may be bliss, but there are some situations where it doesn't apply. she may take your ignorance in a negative connotation.

being Друзья is optional with the boy (if that's what you're referring to), but only if Ты feel comfortable with it.

i suggest Ты tell your friend that Ты didn't want her to tell everyone about it, and that personal information like this is meant to be kept between friends, not become some petty gossip story. as for the boy, Ты could probably Подтвердить the feelings Ты have for him, but in reality what Ты do is up to you.

Ты could easily ignore everything i said, that's fine. in reality, Ты control what happens next. i'm just giving Ты different Просмотры so that Ты can choose your path carefully

ignore the problem and pretend it's not awkward. it only makes it worse if Ты make a big deal out of it.

Well maybe your friend didn't mean to make Ты feel embarrassed by her telling your crush that Ты like him, she might have wanted to let him know so Ты wouldn't have to tell him. I think Ты should ignore the problem или try to tell her that Ты didn't like what she did....but I'm guessing that Ты two aren't very good Друзья anyway if Ты want to kill her so badly....

Why is this such a big deal?

I mean, he now knows Ты like him right?

I'd just forget the problem, because it doesn't really seem like one.

Ты choose what Ты think is right/needs to be done. Just know you'll go to jail if Ты kill her. ^-^

Ты can choose whichever Ты think is right. I personally would just ignore the problem and not make a big deal out of it and I would not kill her. She's your friend,sure she told him Ты liked him in front of everybody but Ты can simply ignore her for a bit until she realizes she shouldn't have done that. Deciding to kill her is taking things way too far and will just make еще problems.

Why do Ты care so much about the problem if it's already been сказал(-а) in front of people?
Having fear of something Ты think is not okay isn't a bad thing, if Ты want to set things right then do it.

All of the above.

Well did this boy accept you?
