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 आप 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. आप disclosed this information to her, and if आप didn't want her to say anything, why didn't आप tell that to her?"
now, i'm not saying आप didn't. i don't know if आप 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 आप A FRIEND. REVENGE, या 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 फ्रेंड्स is optional with the boy (if that's what you're referring to), but only if आप feel comfortable with it.

i suggest आप tell your friend that आप 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, आप could probably कन्फर्म the feelings आप have for him, but in reality what आप do is up to you.

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

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

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

Why is this such a big deal?

I mean, he now knows आप like him right?

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

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

आप can choose whichever आप 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 आप liked him in front of everybody but आप 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 और problems.

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

All of the above.

Well did this boy accept you?
