I know I won't go to her house. So was this wrong of me to say? My ex friend who was like my family for year?

If she writes back and tell you not to bring your boyfriend, tell her that you won't be coming. It is a holiday and you will be spending time with your boyfriend. I hope she doesn't expect you to dump him only to visit with her. And since you don't want to be her friend, stop all contact from this point on.
