How do i talk to my friend shes 16 and im almost 16 it seems she only wants to hang out when she has nothing?

elso to do. It used to always be about one of her bestfriends now shes hanging out with a friend of ours constantly who is NOT the greatest influence shes 15 just turned 15 lies to her mom constantly, drinks, and does horrible stuff like that . However she is literally over at this guys house whom i have me.t every single day of the week and just as the cherry on top hes 21 im not jealous i just tired of dealing with this ****. I dont know how to ask her to actually hang out with me I'm actually really close to tears right now. I feel that she uses the fact that i dont really have any other friends what do i do? what do i say. Its like i dont matter and i want to do something and say something that will make her realize what shes doing to me. I want to be the one she constantly asks to hang out with. I want to have her see what shes doing is wrong . I feel left out constantly . It seems as if every single time i get a friend at school and start hanging out with that person she gets clingy and wants to hang out Im so tired of this ****!!!!
