I would be grateful for any advice you could give me. I'm sorry this is long and not entirely about stepchildren... I'm going to try to tell my story in 3 parts because it's so long. 
 

Part 1: The Beginning 

8 years ago I started dating a single dad, "D", to a 13 year old boy. We met on a dating site. At the time I was 27 and I had never dated a man with a kid before, but I was not worried. I have younger brothers around the same age and I enjoyed watching them and being around them and all their friends. In my family, I was the babysitter and I really enjoyed it!
