The answer to that question is a difficult one, because Amy Lee nor Ben Moody ever admitted that they were dating, but if you watch old interviews from before he left the band, its obvious that there was defiantly something going on between them, AND, apparently during a court hearing about the old band manager Amy Lee's attorney,
" well aware that Ms.Lee was recently in a abusive relationship with Ben moody" that implies that yes, they were dating, and he was abusive ( many label this as a rumor though, so it cant be proved) also, Amy Lee was in a relationship with the lead singer of the band Seether in the early 2000's, AND she is currently married to long time friend, Josh Hartzler.

If you mean who started the band Evanescence, the answer is Amy Lee and Ben Moody.
She was playing "I'd Do Anything for Love, But I Won't Do That" by Meatloaf.
Amy and ben moody met at a music camp one summer, and started writing from there
Amy Lee and Ben Moody invented the word "evanescence" from the word "evanesce."
Amy Lee wrote the song Haunted based on a story Ben Moody wrote. When she read the story, she felt compelled to write a song about it.
Amy Lee and former guitarist of the band, Ben Moody formed it together. Amy was playing a song by the band Meat Loaf on the piano at a camp and Ben heard her and convinced her to start a band with him.
Because Amy Lee and Ben Moody did not start the band to express their religious views.
After meeting ben (moody) she spent most of her time with him writing and composing music.
Amy Lee and Ben Moody started the band Evanescence in 1995. They made their first EP in 1998
Haunted is based on a story Ben Moody wrote and presented to Amy Lee to write lyrics to.
