[Rigel]

All I can suggest in situations like this is to practice what you preach. Accept that she isn't the most understanding person in the world and do what you can to keep giving your suggestions in a way that doesn't make her feel threatened. For people like that, it's often best to let them assume they came to the idea themselves. Twist it so it seems like she endorsed it from the beginning and let her have her moment of glory. It's unfortunate that not everyone is willing to take the ideas that come their way and use them for the greater good of the group, but that's the way people are. Too many people make pride a part of it and refuse to consider an idea, regardless of validity, because they feel that it should be their way or none at all. That kind of person is a bulldozer and will do whatever they can to have the reins. Try to befriend her and let her know that, while you respect her opinions (whether you do or not), you feel that she would benefit from listening to your ideas. Let her know in a casual way that a great leader can evaluate criticism and utilize group input to the utmost, and you have faith in her ability to be a great leader.

Or keep going as you are, try to not get in her way, and hope it all ends well. Your call.

Good luck.
