I had a crush on a really cute guy in the beginning of this year. When I first liked him I thought he would be no more than 15, he looked so young, but later on I found out that he is 17 years old and is in the last year of high school. Everyone on the internet told me its our age difference is illegal and told me to give up, but my heart still hurts, he doesn't even know that I exist. What should I do to make myself to feel better?( I am 14 years old G9)

Find people your own age to interact with.

Every boy in my own age seem so immature and I was never intrested in any of them

I do not know what to say, when I was in your age, I was only interested in different kinds of books, cartoons, clothes and some kind of sports, and play with my best friends! And felt happy for that!

While I sympathize, at 14 you should be looking at boys in the 14-16 age group. If you can't find any that interest you, then bide your time. There is no imperative to be dating.

One other point. There are no laws making it illegal for anyone to just date anyone else. What would have been illegal is to have sex when you are under the age of consent. However, the problem at your age, is that boys and girls are at very different stages developmentally. So, even a three year difference is a wide gap they wouldn't even be a concern if you were both in your 20s.

Girls your age are so often impressed when an older boy pays attention to them that they will go to extremes to please them. Boys are well aware of this and will too often take advantage.
