Question for Kobes

Kobes,

The Ninth Commandment says that "[one] shall not covet their neighbor's wife." In principle, I suppose I agree with this statement. If a gal is taken, the gal is taken, and there is no point in getting oneself all worked up for something that will inevitably end in disappointment and rejection.

That being said, let's suppose for the sake of arguement that somone wanted to pursue a girl that already had a boyfriend. Within this hypothetical model, what would be the best way of going about doing it?
