Bride keeps changing Wedding plans ...is this normal?

Dude, time to put your foot down, especially if you're not far from the wedding date... time for you to make some decisions to alleviate some of the insecurities she's having. For one, seems like she's taking everybody's considertation, advice and complaints except that of her future husband. If this is what things are gonna look like, then take this as a sign and get her attention. Right now is the time for you to step in, otherwise at the end it will not go anything close to what you wanted for it to be like. Talk to her right now and YOU finalize many of the things that need to be finalized at this point... I know you're trying to make her happy, but step in as the man of the relationship and make it work. Good luck.
