I tried asking in the parents group but did not get many answers so I've come here

A few months ago, one of my son’s close friends moved in with us. He wasn’t a bad kid, just extremely sheltered. He came from a very wealthy background, attending private school and having gaming rooms. He had anything he wanted and never had to do anything for himself.

However, both of his parents were arrested for embezzlement and tax fraud. They committed several financial crimes, and as a result, all their assets were seized, and he and his siblings were removed from the home.

Adjusting to life outside of that environment has been difficult for him. He went from having everything done for him to learning how to do things on his own. He’d never even picked out his own clothes, so for a while, he wore pajamas all day. Public school has also been a tough transition for him.

Things got even harder when both his siblings were removed from their foster home. His sister, who is 11, was placed in a home for troubled girls due to inappropriate behavior towards men, including her foster father. His brother was admitted to a psychiatric hospital because of mental health struggles and aggression, which left him very concerned about them.

Despite the challenges, he’s been adjusting better lately. He even started working part-time at my son’s job because he was feeling lonely at home. Every day, he’s learning to live with less money and becoming more self-sufficient.

Recently, after they opened presents, I noticed something that concerned me. My son and his friend went outside, and when we checked on them, I saw that he was sitting on my son’s lap while my son had his chin on his shoulder. I couldn’t help but feel that something might be developing between them, and while I’m okay with that, I’m wondering if it could affect our fostering arrangement.

He’s only four months away from turning 18, and I’m unsure if I should have a conversation with them about this. What do you think?
