When my SO and I met, I asked his children if they were okay with it. I knew them before I knew him. I have been in their lives for almost ten years. I knew what a loser as a father he was. He was young when he and his ex GF had them(all illegitimate).He had custody of girls. His son was with the Mom. He picked a woman with no kids after that. She wanted to be princess not the queen. Her parents spoiled them, not his kids. They lived life as though it was just the two of them. So, Aunty (my BFF)played Mom. She has two children around the same age as his.
