Teens : i have an urgent question!!!! ?

Im 15 and my guy friend who is actually not my friend anymore can be both nice and an *** . He often says painfull things to me one of those things was "you have no " and he was serious when he said that. And after awhile i forgave him but last month he called me a ***** infront of alot people ...but it was supposed to be a joke i guess.. But then after that i texted him and i told him he was an *** and once again he was all rude to me and after that day i never spoke to him again . And now im planning this christmas dinner but it will be at my friends house and since its at her house she will also decide who can come .. But she is friends with that boy that i no longer talk to and she and everyone els think that he should come to the x.mas dinner next month . But i totally hate him and i though since i was planning it ..i would say who can come and who can't .but since its at my friends house she can also decide and everyone thinks im being childish and that i should forgive him . But i don't wanto bc im tired of his crap . But im pretty sure that my friend is going to invite him weither i like it or not... And now im not sure how to handle this situation bc i still wanna go to this x.mas diner that i wanted to plan ...another option is to throw the diner at my house but i don't wanna do that bc i don't feel free infront of my mother and etc...but if i do throw the diner at my house i will be deciding who can and can't come but my house is no fun but even if i wanted to throw t he dinner at my house i woulDnt be allowed
