I moved in with my girlfriend about a year and a half ago. She shares custody of her 6 year old daughter with her ex husband. Her daughter spends half the week with us and half with her bio dad.

The issue I am facing is that of my role as a "parent". My GF and her ex have very different views on her upbringing which partly caused thier divorse. Part of the issue now is that my GF has no rules in our house compared to her bio-dad, and over compensates with gifts trying to win her daughters love so that when she gets older she will want to be with us instead of her dad.
