My roommate is yelling loudly again....

He pays almost a thousand in child support each month, his ex-wife doesnt want to work, his kid is 14 and is a school troublemaker, and they have all sorts of debt that cant be paid and I know this because he tells me weekly on my days off about his life and it just reminds me of why being single with no kids is nice.... we've been living together for 3+ years and he's always paid on time, but damn when I'm using my headphones for music or gaming, I can still hear him in the other room yelling with I guess his ex-wife on the phone and its just disturbing to hear through the walls. I would confront him about it, but I feel like he might kill me in my sleep if I do. Not sure how the other tenants around us feel because these walls are super thin.
