Hello, I'm new to this site, been lurking for a while, had a huge fight tonight and still dwelling on it...
I have two bio children with my SO, daughter 5 and son 1. My SO has an 8 yr old daughter whose mother took off when the kid was a few weeks old and hid from him until about 2 yrs ago when his mom found her on facebook.
Although he did tell me about the kid, I never gave it much thought and I guess never realized I would suddenly have a stepdaughter.
