was andy sixx really mean to sandra?nd is that the reason she left?

No. Sandra apparently didn't like the direction Black Veil Brides music was going, so she left. She is now in a new band, Modern Day Escape.

Andy wrote on their Myspace page regarding why she left, but it seems to have gone, so I can't give you a reference to my information.

but now i think sandra wishes she hadnt left cause i think BVB is more successful that her mew band.

No, Andy Wasn't Mean To Sandra. And All I Know Is That Sandra Left To Join The Band, "Modern Day Escape". Sorry If That Didn't Really Answer You're Question. [x

link If you read what it says here you'll see that Sandra left because "they were a little too metal for her."
