How do I communicate with my boyfriend's daughter on facebook?

[hmmm]

Try to establish a friendship relationship with your step daughter. Let her know that its safe and that you are not trying to steal her dad love from her nor are you trying to replace her mother. Make it clear that you want a friendship with her. Perhaps you can start by commenting on some of her comments/pics. Or get her involve with the wedding planning, ask her if she would like to help you out? Don't start by interrogating her life... let her warm up to you little by little. Perhaps, you may ask her if you can do a video conferencing and ask her what her thoughts between you and her dad. What are her expectations of you. Good luck
