but I still call my SO's son my stepson. We have been together a long time. I have been in this child's life since he was 2. I love him more than myself, and like he was my own. My SO and I may or may not get married but we will be together forever. What's wrong with that? We are happy, and consider ourselves a family. A VERY HAPPY FAMILY. I feed him, buy his clothes, help with homework, take care of him when he is sick, get up when he has a nightmare . It doesn't happen much but I'm sick of those bitches that feel they have to make it a point to say "your not his stepmom". Technically no, I do not have a piece of paper saying that they are my family. But in my heart and soul, they are mine. So suck it.
