My cousins are ruining their lives?

Ok, so my Aunt Mary's children, Collen and Ryan, are ruining their lives. Collen is so smart, she left Yale, where she had a full scholership, to live with her boyfriend who is 10 years older than her and works at Mcdonalds. That was stupid, no duh. And Ryan got his girlfriend prego, and now the baby (Kylie Rose) is 18 months, and they went to court and now Ryan only gets her 25 days a year. And then he got a new girlfriend, Melissa, who broke up with him about 2 months ago. And then she called him a month and a half ago, and she's pregnet with his baby. He never even went to school after high school. I am just really concerned. What should I do? I don't want to talk to them, that would be so akward
