In 1981, Evans came very close to leaving U2 for religious reasons, but he was persuaded to stay. During this time, he became involved with a group called Shalom Tigers. Bono and Larry Mullen Jr. were also involved in this group. Shortly after deciding to remain with the band, he wrote a piece of music that later became "Sunday Bloody Sunday". The Edge married his high school girlfriend Aislinn O'Sullivan on 12 July 1983. The couple had three daughters together: Hollie in 1984, Arran in 1985 and Blue Angel in 1989. The couple separated in 1990, but were unable to get officially divorced until 1996 because of Irish laws regarding marriage; divorce was made legal in 1995.
