"I didn't have the guts to wake up to his violence earlier," she said.
She said a doctor prescribed her anti-depressants in 1995 and said her former husband robbed her kids of their childhood and she feels guilty of not protecting them.
Ms Cochrane said she thought of taking her own life a number of times but couldn't do it.
"I never had the chance to share the special bond with my kids. I am a victim of violence but more importantly my children became victims. Unfortunately I can't give their childhood back," she said in court today.
"I don't hate him but hate myself for what he did to me. My life was his to do as he wanted. For once I don't have to worry about getting punished. You held me prisoner for 22 years. Now it's your turn to feel what we went through."
Titford came to prominence in the late 1980s and early 1990s over a dispute with the Crown over a farm he owned at Maunganui Bluff.
The land was subject to a claim by Maori and was eventually bought by the Crown to give to the hapu. Titford claimed that the hapu had torched his home and caused plenty of other damage to his farm during the dispute.
But the verdicts show that he made up many of his claims.
Titford was a Mayoral candidate for the Far North in last month's local body elections and his trial was held during the campaign. However, suppression orders in place at the time prevented the media from revealing that fact he was on trial.
The previous longest jail term handed out in Northland was to convicted murderer Wayne Bracken, 36, last year. Bracken was sentenced to life in jail with a minimum non parole period of 21 years for the murder of Aucklander Jack Davis on February 25, 2011.
