Surprise from my past

I've succeeded in my career and hadn't yet married at 34 for some reason I dated but hadn't found the right woman. I thought I had while at university, but she (a year younger) left suddenly no reason was given she had just vanished. I graduated and started my career and dated other women, always had a missing something feeling. Then one day last June I came into the offices and saw a woman I thought I recognized. But couldn't place, she was there for a job interview, several were available including an assistant for me. But our HR section does all the hiring, I was given a list of possible assistants by HR for me to choose from. Only one name I recognized, and it was my college vanishing girlfriend the woman I thought I recognized. She was marked lowest of the listed names as she hadn't finish college. I chose her mainly to solve the mystery why she suddenly left with no contact with me first. She was also the youngest on the list and so HR didn't ask why I'd chosen her, I guessed they assumed it was her age. Next day she started as my assistant, and she did recognize me almost straight away. It turned out her father had died, and her mother was already very ill, and she had to return home to care for her now departed mother. She also told me I was father to her 12year old daughter, she was pregnant before she left, just didn't know it at the time. Shocked and delighted at the same time, she was busy with her ill mother and also pregnant and then had a baby and her mother to care for after the birth. Her life was hectic almost all the time, only slowing down a little 3 years after her departure. Then her mother finally passed away a year before she applied for the job. Had a job for a time only to lose it in a restructure, so she applied at my workplace. I was quite willing to meet my daughter and on meeting her, I saw where they were living. It was okay, but not somewhere I would want to live. So, I suggested they move in with me and as it was closer to my daughter's school they agreed. HR was somewhat surprised how quick I'd gotten my assistant to move in with me. But on me telling them she was my old girlfriend, and her daughter was also mine. That stopped the lecture they would've given otherwise. My girlfriend had her own room as did our daughter, but as time passed, we rekindled our romance. Marrying in November, my wife/assistant is now pregnant again. My life now seems to be perfect, that missing something feeling gone.
