In family

Hello, so my story begins at age of 6.. my mother’s brother was using me sexually and I remember it very well, my mother never believed me. I told my current boyfriend and he is ready to throw punches and I just don’t know how to stop him from doing that because I don’t want to lose my family just for the truth.. anybody else been in a similar situation? I’m 18 by the way, oh and my boyfriend did get me pregnant and my family doesn’t know yet, I’m thinking of telling after I get the second ultrasound in February. Thank you for taking time to read this..
