Trigger warning: drinking, abusive relation, mentions of toxic relationships, underage drinking

A and B are married and adopted a son, C. Now A and B have always been happy but they started to... Change. Less happy with each other.
A started to drink and B tried to stop him but that just ended up in fights. When A started to get abusive B tried to hide it from C but.... C still heard.... C new from a young age what was happening.
Years later C is looking for comfort in other men but that doesn't work out well. He is used and cheated on.
Then they get home in tears only to hear fighting. C growls and gets a bottle of A's beer and sighs.
"Dad does it... Why can't I?" And he started to drink it. At first he hated the taste but soon loved the feeling
