I know the feeling because not only did I use to do that but my friends both were obessed with their crushes. Ok I can give you the best advice that a 12 year old can give: Talk to her, ask her once if she wouldn't mind to stop talking about him for a while. Don't ask her after that because that will make her feel like shes annoying and that you aren't a very good best friend.
But then again you could ask her, do you really like him for him? Or is it because his cute, hot etc... Because once she realizes if she really likes him, or it's because everyone thinks his hot then she might realize that she made a mistake and you would be her hero for making her realize she was making a mistake. Nicole just may be extremely excited that her crush is 'the perfect guy for her', don't try to talk her out of liking him because friends are there to help and give advice.
Also do not try ruining for her if you had enough by telling Matt that Nicole is madly inlove. That will just ruin your friendship, (although I am sure you will not do such a thing). Now, if Nicole only ever talks about him then try changing the topic whenever she brings him up.
Or make up an inside joke that you can both laugh about and she might have more fun talking about it. If none of these things work try pretending you too have a crush, maybe not from this school. Jason from your kinder, you talk to him all the time on facebook/msn etc.. Just convince her theres a guy for you out there too, (whether there is or not).
Talk about Jason all the time so she can see how irritating it is for you and slowly it should improve her talking about Matt. If this too doesn't work why not try to set them up as a couple, does Matt like Nicole secretly? At recess or lunchtime invite him with other guys and girls to truth and dare, (don't forget to include Nicole).
When it gets to Matt, ask him "Truth or Dare" and if he says truth, say do you like anyone? If he says yes, then the next time Nicoles at home sick or absent from school. Do another truth or dare, but make sure the first time went well otherwise they won't be as keen on playing the game.
Ask Matt who he likes, hopefully he might overhear you and Nicole talking about things that he likes and Nicole and things will click from there. But most importantly support Nicole, as much as her raving on about Matt may annoy you, be supportive! Crushes are truely important to every girl and guy.
It's a cute way of life. Hope that helped! :).
Same here but my bffs crush is my brother she hangs around him all the time talks about him all the time and I'm just like shut up! But I talked to her about and she felt really bad and said she was sorry and now it's not a problem.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
