Good lord, help me decide what to do.

I would keep it.

Everytime in my life when I've had a little voice inside tell me what to do and I've ignored it, I've totally regretted it.

BTW, I've been struggling with the same issue over my Petrol Spy. But I do love it, and so I'll keep it.

Good luck!

If you're planning to purchase another bag i'd sell it. Put the money towards the new purchase. The BV is regular stock so its not like it cant be replace.
 
I personally would try and use it for a month or so to make sure you don't love it. It took me about a week to love my Speedy 30 (so much bigger than the Speedy 25 I had been using) - After that week though, I ended up giving my 25 to my daughter, I loved the 30 so much.

The BV and BH are both gorgeous bags. Even if you get a good price, you will be taking a financial loss so I would be really sure before you sell it that you don't really like it. I would put away all your other bags for at least a few weeks, use it exclusively, and just be really sure.
