I miss my nephew long rant please read

Ok so a few weeks back in early January I my brother and my sister got into a HUGEEEE fight! (Me and my sister against him) long story short he’s an asshole and would blast loud music purposely while i tried to sleep for work and school( im a 17yr HS senior) he’s a 21 year old who used to live at my moms he has no job he has a 1 almost 2 year old son who he barley cares for and his baby mama which is his girlfriend also lived there he only helped my mom with one very cheap bill and he always paid it late. Ok so let me wrap it up the night of the fight he broke my phone into pieces literally and he also punch me and my sister constantly like i said a fight. She only hit him because he hit me first (she’s 21) and my mom had to leave work (she works at night) to come home before then she called my grandma’s one from her side and my dad side and my dad also came by to stop the fight and told me to leave with him and I didn’t wanna. Ok so again LSS he told my sister find her real family ( she’s adopted but that doesn’t matter) and my mom kicked them out and my nephew let with them of course but ever since he left he’s been super sad and doesn’t look the same at all. I miss him so much. we were sooo tight i know he’s only 1 but still i know for a fact he won’t ever let me see him agin. I left out a few parts but i had to get to the point
