Leach was married

Following Alive or Just Breathing ‘ s release, the band expanded to a fivesome; Dutkiewicz moved to guitar and former Aftershock drummer Tom Gomes filled in the vacant drummer position. After Leach was married on April 20, 2002 and began touring again, he fell into a depression , which affected his performances. Leach’s screaming vocals came across more emotionally driven instead of powerful, and while on tour, he would spend long hours in the tour bus only to come out to perform the shows and immediately retreat back to the bus. Leach left the band a few days before Killswitch Engage was meant to play a show and sent the band members an email telling them he had quit. Leach remarked, “I didn’t have the mental energy to face them, or even call them on the phone. Rather, I was at a point in my life where I just didn’t want to face any of them so I wrote them a long email explaining, like, I’m just done.” D’Antonio said in an interview that “after three years of hanging out with the dude, and considering him a brother, to just get an email was a little bit harsh”.
