I will be quick and easy, there is a girl in my high school that I am very attracted to, and everything seems to indicate that she also likes me, these last 2 days we have been very affectionate and she even uploaded me to her WhatsApp and Instagram statuses, which I also did, so, if everything is going so well, will you say, "what the hell is going on"?

Well, today she wasn't very cheerful, she didn't get very close to me, sometimes she ignored me, I went up to her and hugged her, and it was quite a "romantic" moment? Even today he bit me 2 times on my shoulder and my trapezius. But there are 2 friends of theirs who are always with them, and they treat each other... Strange, very affectionate, strange hugs, lots of hand holding, and one of those boys even sat on her lap today. I sent her a message today and she didn't respond either, she was doing homework, but she logged in to set up statuses on WhatsApp... So??? Although today he told me a lot about his love and today I went on his Instagram story, but still... I don't know. And the real problem is that... I don't know whether to declare myself to her, they have told me not to declare that I want something with her, do I tell her or not? I feel like I'm someone else from the rest of her "suitors" I want to stand out... Any advice?
