I can't stand Bridezillas, and that is what girlfriend number one sounds like she's well on the road to becoming. Even brides have to realize that money and time have to be taken into consideration when asking someone to be in/attend the wedding. Beyond the bride's field of vision, the rest of the world is going on and sometimes people can't make impossible changes in their lives to accommodate her. She needs to face that.
PS Sorry if this is harsh, but out-of-control bridezillas really get on my last nerve
