Another stepmother here. Thankfully, we have no real issues with DD. Not to say we didn't have our share of heartbreaks with her. At 13 she decided she wanted to live with us. We were thrilled and welcomed her wtih open arms. However, she went from her mother's house with little to no rules. To our house with rules. She lasted about six months and went back to her mother. What hurt the most, was she had her mother call and tell us. She felt that she needed to be with her mother. Did she did admit to me last year (when I was relating the problems my boss was having with his daughter) that she made a mistake. She should have never moved back in with her mother. Her mother allowed her to drop out of high school. Didn't care if she went to school. She realizes that if she had stayed with us, she would have finished school. But it is tough being a step parent. It is a strange netherworld. You are not the biological parent, yet you are an influence in the child's life. DD is now 27 and we have a good relationship. She realizes and fully admits that I treat her better than her mother.
