My ex girlfriend doesnt wanna b friends and lied to me about y she wanted to break up?

my ex broke up with me and she is 13 i found out from her bestfriend that she doesnt wanna b friends but maybe later, r families r really close and we had a good friendship going before we starting going out cause she really liked me. her best friend told me this and that the reason she broke up mainly is because she didnt likie me anymore. but the reason my ex told me is beacuase she wasnt ready for a boyfriend and was scared of the idea of having a biyfriend, so she lied to me. we went out for over a month, longer then any of her past relationships had. but my question is do u really think will nvr b friends again? please throw in any other advice on my situation
