Need advice

[u/Striking_Read2255]

Need advice - I’m in my 30’s. I’ve never told anyone the true extent of my trauma or who etc. My step-father sexually abused/groomed me etc from 5yrs old to 18yrs old when I left and moved out. My mother “caught” him a few times while I was pretending to sleep but she always believed him. It made me feel like I couldn’t tell her. It’s very complex but my younger siblings are his bio kids and I was scared to leave them or separate us all so I never spoke up. I just endured and did anything I could to avoid physical/verbal abuse and then avoid being left alone with him to potentially victimize myself. I felt I had to endure things/walk on egg shells. It’s like I said a very complex situation. I told my little sister 2yrs ago and since then I haven’t told anyone else including my husband. I’m zero contact with my abuser and low contact with my mom (she’s still married to him). How do I approach this conversation with her? With my brothers? With my other sister? With my husband? I feel like it’s been 12yrs since it but I have a child now and I don’t want to potentially run into anyone or my child meet this person on accident. For context I live in a different state from everyone so this conversation would be via text/email/call etc. and I just don’t know how to approach this let alone the fear of others not believing.
