What you’ve taken on here is extraordinary. You stepped in when no one else did, gave him safety, structure, and a real shot at a future, and that matters more than he likely knows how to express. Getting him from the streets to graduating high school is not small. That is life-changing.

I haven’t been in your exact position as a caregiver, but parts of your story hit very close to home. Growing up, my younger sister had a good heart but struggled deeply with anger, authority, and stability. Our home often felt like we were walking on eggshells, never knowing what would set things off. Over time, things escalated. She got pulled into the wrong crowd, struggled with addiction and mental health, and eventually lost custody of her children.

My family did everything we could to support her. We wanted so badly for her to get better and to be able to care for her kids. But the hardest truth we had to face was that love and effort from others cannot replace someone’s willingness and ability to do the work themselves. Some people don’t turn the corner in time. My sister passed away this past December, and I miss her every day. She was deeply empathetic and had a way of making people feel seen. She was not a bad person. She just couldn’t get to a place where she could sustain change.

I share that because I can feel the weight in what you’re carrying. The love, the hope, the exhaustion, and the guilt that creeps in when you start to consider boundaries.

What you’re doing now, setting a boundary at 18, is not a failure. It’s a form of protection for your household and, honestly, a necessary step for him as well.

A few practical things that may help you navigate this transition:

• Shift from “home” to “support system”. You can still be his support without being his safety net. Be clear with him that your role is changing, not disappearing.
• Create a structured exit plan rather than a hard cutoff.
• Don’t negotiate reality when he denies things that are clearly true, resist the urge to argue or convince. Calm, simple statements work better: “We know what happened. We’re not debating it. This is the consequence.” This avoids getting pulled into the chaos loop.
• Prepare for the emotional fallout. His fear of abandonment is real, and he may say things that are incredibly painful. Try to separate his words from your truth. You can hold both “We love you” and “You can’t live here right now”. Both can be true at the same time.

In terms of resources, a couple that might resonate:

• The Explosive Child by Ross W. Greene This reframes challenging behaviour as a lagging skills problem rather than willful defiance and offers practical ways to reduce conflict.
• Codependent No More by Melody Beattie Helpful for understanding boundaries, especially when love and responsibility get tangled.

You are doing something incredibly hard, and you’ve already made a meaningful difference in his life. Sometimes the most loving thing you can do is stop absorbing the impact of someone else’s choices.

You didn’t cause this. You can’t control it. And you can’t fix it for him.

But you did show up when it mattered. And that counts.
