Muslim step father preventing a non-believing father from visiting his child

Q: I have married a woman who has one childern (6 year old girl) with a non believer. The childs father wants to visit his daughter and take her for weekends with him. He is taking her with him to pubs where people are non believers, drinking alcohol and smoking cigarettes. Do I have a right as her stepfather not to allow this visiting, etc.?
