To clarify, let's say you're in a group setting with a girl you're interested in and you know she is already somewhat into you, but being a high value man in demand you also flirt and hang out with other women who also shows signs of interest.

How far should one go with these other women if you're overarching objective is to make the original girl desire you more, but not overdo it to the point where she counts you off as a relationship opportunity?
