Ok... So I've been in a relationship with my BF for over 5 years now. We each have a daughter. Mine is 9 and his is 7. I literally can't stand his kid. I am so annoyed by her, that I don't know what to do anymore. She lies constantly, breaks my belongings, and whines and cries over everything. In the beginning, I opened my life to that little girl. Her mom was a drug addict, so she was constantly abandoned, over n over. I was 100% there for my SD, and opened my life, my house, my heart, my family, and then some...to that little girl.
