HELP...What would you do in this situation?

Alright friends I’m really needing some guidance. What would you do in this situation?

A friend of mine (we’ll call him W) is 21 years old and is still living this is parents with his 15 year old brother.

I’m the past year, the parents have split up and go back together honestly about 20 times.

In the past month, the father has moved out leaving the mother, my friend W and his brother.

His father is a drug addict (getting clean) and his mother is an alcoholic. The mother continuously drinks every night and goes out with friends (especially during this whole stay at home order in place) while my friend W is home taking care of his brother.

My friend W always tells his mom how he feels about her drinking and not being home for his younger brother.

She told my friend W and his brother that they were gonna need to stay paying bills or they can get out. Then proceeded to say that if they didn’t like that then she was gonna move out.

My friend W has a stable job and is financially good right now but adding in the mixed of a teenage to take care will definitely hold him back financially as well as his timeline for things.

What do you suggest my friend do?

-Move out leaving his brother ?

-Have my friend and his brother move out to a family/friends house ?

-Get DCF involved ?

-???

I don’t know how to help and it hurts to see my friend go through this. My friend do want his mom to get in trouble but honestly I say forget her. I just want my friend to do what right for him and his brother.

Thank you everyone during this crazy time.
