AITA for hating my childhood friends mother

ok so i have been best friends with a girl same age as me since we where babies when i turned 13 tho our friendship ended over something kinda stupid imo for a short summery i had sent a song to her and she played it in front of her mother and apparently it had one cuss word in it they are very strict and religious (they are christian) the very same day her mother contacted mine and said that i have been bullying her and how im not a good infuence pretty much they spectilated that i was gay and liked girls …i dont im happily in a relationship with a wonderful guy but at the time this happened i had no intrest in guys so i understand where they where thinking i was into women but they agreed ( our folks) that we would only calll if we wanted to talk so no misundertanding can happen again the very next day later i was talking to my friends / cousins in a gc she is also in this gc and then "she" sent a very long mgs saying how i have bullyed her been rude and not one of god not to mention how our folks told us not to talk again keep in mind my mother never agreed to this and this was never talked about and so on this is the short summery this mgs was massive and there was a lot of things in it when i saw it at first i was mad and was typing a responce but then i had just gone to my mother and broke down telling her everything that happened she was pissed and a lot of things happened that day for starters she mgs my friends mother asking what was this and that this was not agreed apon but the mother said she didnt want her child to be bullyed and that shes seen our mgs and how im a bad friend and how she says i am gay this women then addmited to the most crazyest shit ever she apparently had been reading our mgs AND responding as her daugther whenever she wasnt there and no she never told me hey this is your friends mother SHE RESPONDED TO THE MGS LIKE SHE WAS MY FRIEND in hindsight i should have relizd something was off since at times her mgs where dry or just weird keep in mind this is a 13 year old friendship i have memories of sleepovers at there house and so on its just still amazes me how all of this started thanks to one song years later i am now thinking of her and her mother since i have heard things from my own mother about how my friend doesnt want to drive and so on keep like not even wanting to go to collage i honestly feel bad for my friend ik she didnt say any of the hurtful mgs shes always been kind and understanding its just her mother is idk they baby her and shelter her im just worried for her future and i want to make things right at least try to befriend her again but idk how to or where to even start knowing her mother she will prob do something like she did before when we where kids any advice would be greatly apprecated i have aready posted this before but im thinking ill get more adivce on here why im asking if i am the a hole is bc i might have been to loud or rude on accedent i am normally very polite but around friends i can make jokes and so on so maybe i did come off a bully idk i cant think of any situation where i have but im worried for if i do contact her what if she hates me and so on idk i just miss my best friend i use to tell her everything and we got along so well
