I am the BM of 2 beautiful girls. The oldest is 12 & she is the SD to my current husband. She has lived with us for about 9-1\2 years. Her relationship with her SF is horrible. He can be a hard ass, and she can be very disrespectful. I think I may be partial to blame in this. I allowed SF to make and enforce the rules and I was the " 'ol softy". This resulted in SF being painted as "the bad guy". Now things were fine up until just the past year. IDK if its the puberty setting in or the fact that her BIO-Father has just come back into her life full time.
