No idea what this has to do with the invisible sky daddy, but here's how I read this
1) You have a problem with women who are comfortable with their own sexuality. This isn't the year 1564. It doesn't reduce her value so long as she doesn't have some weird disease. "Sloppy seconds"? You had no problem fucking her. Why should he?
2) You're a guy who satisfied her sexual desires for a little while, which was all she wanted for a while. Now she wants to settle down and is looking for other qualities. As you implied, in her culture, a big one might be a guy who doesn't mind taking care of her parents.
