<human>: I've been at this for two hours now. I don't know what to say and what to leave out. I got pregnant as a teen by a man who didn't want to parent. I moved on, moved, married, had kids. My son was raised by my now husband. How do we bring this up? What age is appropriate? When my son was so small this didn't seem like such an enormous lie. And now when I see my young man I'm so troubled. My husband was adopted, and feels strongly that your parent is the one who raised you not who made you. And that when the time comes, we will tell him and give him the resources to reach out if he chooses. At first I had thought maybe I'd never tell him. What if he was mad at me? What would I say? The truth is that his bio dad was an addict who abused me, broke into my home, threatened to kill me and never wanted anything to do with him. I didn't want my sweet boy to ever know or think that's where he came from. 

I was recently contacted by my ex. He wanted forgiveness for the abuse I endured. He said he had been carrying around shame and guilt that was holding him back and needed to apologize. 

This brought all my unresolved questions flooding back. How do you unearth a lie like this without burying yourself? I know for so many people issues surrounding there biological parents forever echo in there lives. 

We are a happy family. How do I not ruin it? My past is haunting me.
