Women and mothers - need your advice

Hi there ladies hope you read this.

Im 28 m with my own struggles but this thread isnt about me. Its about my younger brother whos 15 and my mother.

I dont live with them and in fact I am in seperate countries from them.

I know my little bro watches porn. Fact is hes already dropping out of class, even went 5 months no school. Ive shown him some videos but hes still so young I dont think he understands the weight of what porn can do to a man.

Hes become very aggressive, abusive even. He swears a lot and causes my mother a lot of pain and anger. Hes broken doors in the house etc..

Her husband is probably an addict because Ive told him about Nofap and there are no light bulbs that go off for him To him its all natural. I feel sorry for my mother and her marriage. Husband is also very irritable and angry most of the time.

Ive told my mother about my own addiction, but only to shed light on my little brother and the times we live in.

She seems to understand and I want to give her some resources while I attempt to persuade my little bro to try nofap.

She can be very explosive and emotional, punishing him etc.. which can feed the addiction (when you want to escape reality and not deal with it) which is really counterproductive.

What resources can I start her off on as a mother and a parent so she can get an idea of the pain most suffer through when they try to give it up.

I really want to help her and my little bro.
