This happened a few years ago, but it still haunts me to this day and i need to know if I’m the asshole.

I (19 f) was sexually abused by my OLDER brother (22 m) for 2 years when we were younger (8 years old and 11 years old - 10 years old and 13 years old). i told my parents when i was 10. I don’t have a great relationship with my parents now, as they have expressed that they don’t truly believe that it happened. they’ve always taken my brother’s side on everything. he continued living in the house until he was 20.

Here comes the issue…

a few years ago, my parents, me, and my YOUNGER brother (around 11 at the time) went to tennessee for a baseball tournament he was playing in. the team he was on was a good team, and the parents got along well. i got along really well with one of the parents, we’ll call her “Mary”. One night mary and i were chatting outside the hotel the team was staying at. we began talking about deeper things, and i almost saw her as a mother figure (hence my and my mother not being close). i told her about what happened when i was younger, and made sure to clarify that DSS had been involved twice before and that my parents know (to ensure she knew i wasn’t still being abused). she ended up asking how my parents reacted and i told her the truth. that they didn’t believe me and my brother stayed in the home. she got upset and told me she understood now why me and my mother don’t get along (she witnessed us arguing earlier that day and took my moms side.) we finished up the conversation and i went back inside.

a couple weeks later, i hear my mom storming up the stairs to my room. “WHO THE HELL DID YOU TELL?!” she screamed at me. i was confused about what she was talking about. she informed me that DSS had been called again and that Mary had told the head coaches. my father (one of the coaches on my brothers team) and my brother were kicked off the team. i felt so mortified that my brother was punished for something he doesn’t even know about. i began to defend myself to my mother saying that i can tell whoever i want. it’s my trauma, my story, my right. my oldest sister then called me and went off on me, saying that what happened when i was younger has been dealt with and that im safe and shouldn’t be telling anyone. welp.

i eventually started feeling like i was in the wrong and that i should’ve just kept my story to myself. idk what to feel at this point. please let me know what you think.

EDIT: my parents put my older brother in therapy for about a month then took him out because he “wasn’t opening up”. thats the only reproduction i’m aware of.
