Maybe this can inspire you. Especially his story in the beginning about some alpha male stealing the show.

First reaction - "feeling sorry for myself".
Second reaction - "try to challenge the alpha male".
Third...? Check out the video.
When it comes to women, there is no such thing as a "bro". Every man in the room means competition, and you are all on your own. There are guys that may spoil your game because they are unaware of what they are doing and how the game works. There are also guys who may spoil your game just because they want the girls themselves. In any case, I think the video above explains the most appropriate action to take quite well.
