long term Guerilla war in Ireland

in 1922-23 the new formed Irish Free State was racked by Civil War, at the same time Northern Ireland had its first Troubles, so is it possible for a long term Guerilla war (lasting at lest 8 years) across the whole island?

If you have Britain decide to let the South keep the North its possible.
