Married and casual?

My bd was married. I know I'm horrible. We were sleeping together for 5 years before I got pregnant. He ghosted me and I was postpartum so I told his wife. They are now separated and he told me to die a slow death along with our child. His BFF said if I think he cares, S'more lost than he thought. Now he's trying to get me to sleep with his BFF. Still wants to sleep with me. Has never acknowledged our child. He said, all of this your fault bc you caught feels. Yes... after 5 years. After you living with me 2 of those years. After you telling me things. But we never kissed
He didn't sleep with me. And we never went out. I feel so much guilt. I love him. He thinks I'm trash. A whore. How dumb am I? How do I get past this? Is this my fault? Should I even try to keep him, as friends, in my life? Ty ty!
