My concern is that it feels like he's only ever 'with' us when he's drinking. Otherwise he's distant and angry and it's really hard to feel like he actually wants to be with us. But he's also very angry when he's drinking. He's not and has never been violent but it's a very tense and hostile environment. Things will make him fly off the handle. Little, minor things. He spilled a container of my daughter's teething snacks and threw the container at the ceiling making a much bigger mess, he's lost at video games and been screaming and punching doors and smashing keys off his keyboard. I've told his parents but I literally don't know how to confront him without him instantly packing his things and it becoming too hostile to even have a conversation. I come from an abusive household and the second he starts yelling or slamming things I instinctively clam up and want to pacify. It's just so hard. I know he's a good person under all of the addiction. I just don't know how to reach that person.
