How do I get her to like me because she's falling for some other kid I just need to get her attention that way she sees what kind of a guy I am

How old are the two of you? Does she know you exist?
If she is interested in someone else, you are out of luck, at least until or if she stops liking the other guy. You can't make someone like you.

We are only 16 and 17 ,and yes she knows I exist. We talk and we have a thing going on I just want her attention to be away from him

If her attention is with him, it is where she wants to to be. This is her choice. You just have to face it and deal with it.

OK thank you

Don't let someone tell you what you should do or not do.I say if you like this girl enough you go for it but if it doesn't work out then it doesn't work out it always worth it in a chance
