A work colleague's mother

I'm 40 and work at a major supply facility, there are about 50+ staff working there, and I was single never married. A new worker was hired and only 16 at the time not doing great at school left to get a job and help out his mother 33 with living costs. She was divorced seven years ago after her husband abandoned them and after 2 years, she divorced him. Where he is they don't know or care. As I was his assigned trainer, I got to meet his mother and we started dating after a few weeks and became lovers and they moved in with me. I got her pregnant after she accepted my proposal and we're now married, and the baby is due within weeks.
