Wow. It sounds like a really cool bag to have and what an experience buying her!
That said, it sounds like there are some other issues at work here and certainly sometimes the bag you think is it at the time, just doesn't mesh with your lifestyle for some reason or another...
If you really aren't up for breaking in this bag--and all that it entails in terms of bumps and bruises along the way--for whatever reason-- then the suggestions to sell it, trade it, or keep it as a display bag are all really great ideas.
As RBB0 said, you do have great taste, so I'm certain that you'll find the right bag if this one just isn't it.
In fact, you can sell it, then go to Paris and make a new memory of a new bag that you will want to carry!!
