My step daughter is 16. She has sex with boys just to b in, but lies about it. She admitted that she wants to get me and her dad divorced. She blames me for the breakup with boyfriend, few months ago she got home late a few times, the last time we took her phone 4 punishment. She tells everyone it was me, her dad didnt know. She says love u baby to 4 boys, when i asked her bf bout it, im the reason they broke up, i thought they were broken up. Now she hates me and makes me bad where ever she goes. What can i do to show her i realy love her, and wants to help her not to mess her life up. As she didnt even do good in school. Plz help
