I was 7 When it all started, Every single day/night i would witness my dad and my son in law fight hand to hand and always having an argument, He was always drinking and hitting my sister (The middle one) I used to stay with them as a child and couldnt do a thing, Now that he has left them now that me and my sister can breath a sigh of relief, Now that i am 16 every single day that i see my sister i regret for being unable to do anything, Yesterday we got a text from my sister and my mother and father went to get my sister (older one) Apparently he was pretty drunk aswell and were fighting, then we figured out he also hit her in the past. Im so pissed, But hey my sister still got back with him
