I just saw that eight-year-old boy this morning. He's now thirteen years old.

I was in the process of adopting him when we separated, so she terminated that process, and I have no legal rights to him as a son. Five months after the separation, she decided it would be best for him not to see or speak with me again. To this day, I still have no explanation why she did that. Maybe one of the two guys she slept with prior to our separation could tell you, but I sure can't.
She's remarried now, and most of this stuff is behind all of us. I see my (ex-?)son on occasion, but we don't get to hang out as a family at all. I expect that to change, as they are planning on moving to my town next summer. I love and miss that kid so much it makes me cry, and I know he loves and misses me as well. Deep down, I believe that relationship will rebuild.
