Wow....Maybe he wants a ready made family or maybe he thinks a woman with kids is mature. I dated a girl with a kid last year and one of the biggest advantages of her having a kid was she didn't have time to nag me. She wasn't concerned about where I was or if I called her. She was devoted to her son and I loved. Maybe he's a guy like me and loves his space and appreciates that you have other priorities that will allow you guys to take it slow.
