I agree that most gender traits are socially constructed.
The reason why some women might seem indecisive is that they have been taught that being otherwise makes them a bitch. I do not know how to overcome that teaching as it is very ingrained in some women. Once the person gets to know and trust you more, they might feel more comfortable in making a decision. If making a decision is too threatening for the person, perhaps, you could come up with several movies that you would like to see and they can pick from among them. That way, the person doesn't have to worry about making a decision that you won't like. I know it is silly but sometimes taking a little pressure off someone can help them make decisions.
