TV presenter Jonsson, 53, was in a relationship with Stan Collymore when he dragged her to the ground and kicked her in the head in a Paris pub at the 1998 World Cup.
But despite the horrific attack having taken place in front of many witnesses, Jonsson has said she chose not to speak about it even when approached by domestic abuse charities because she felt it was "insignificant" compared to what other women were going through.
Writing in her Sun column, Jonsson explained: "I did not because I felt that his one flash of hatred and fury felt so minimal, so reduced, so insignificant when I measured it against the suffering of other women who were being pummelled daily."
Adding that she would have felt "fraudulent" and "attention-seeking", Jonsson said she now regrets not having used it as an opportunity to discuss controlling relationships.
She wrote: "I regret that now. I wish I had had the broad shoulders to carry my pain forth and explain that attached to the striker’s foot was a long list of moments in time and incidents when the mental persecution and torment he meted out daily, had damaged me more than his kicks.
"I wish I had drawn attention to the fact that abuse comes in so many forms and not just the physical punishment. But the psychological and emotional destruction can often be so much worse."
Jonsson was writing about the attack, and two other occasions on which she was hit by men, after watching a video that Spice Girl Mel B made with Women's Aid to draw attention to domestic violence victims after a year spent in lockdown with their abusers.
Mel claims to have been in an abusive marriage with ex-husband Stephen Belafonte which she has said left her suicidal at one point.
Jonsson described herself as "deeply shaken" by the video, which shows Mel performing a contemporary dance to act out a violent relationship and her escape from it, and said it "triggered some unpleasant memories".
