It sounds like she likes the attention. In and of itself that might not be too horrible. But it doesn't sound like you can handle it. And when you say
cause i don't wanna be perceived as insecure or jealous..
I think you are misinterpreting your own feelings. You are insecure and jealous. You believe that the attention that others give her will eventually lead her to want to be with one of them rather than with you. That is jealousy. However, if you are more concerned that she doesn't like you enough, that is insecurity. Your frustration is just your emotional response to the jealousy and insecurity.
Now, I am not saying that you shouldn't be jealous or insecure (although I don't think you need to be), but you can't MAKE someone feel the same way about attention from others like you do. You can either deal with it or it may be a deal-breaker.
Good luck.
