Vicky Pryce broke down in tears as she told Southwark Crown Court how she fell pregnant in 1990 while married to the future minister, but he made her terminate the pregnancy.
'I got accidentally pregnant and obviously wanted to keep the baby because it was healthy - in fact, I quite like babies, that's why I have so many,' the mother of five said.
'He absolutely resisted it, saying it was bad timing, bad financially, bad for his career to be tied down again. And despite my protestations, he got me to have an abortion, which I have regretted ever since.'
Pryce, an economist, is currently standing trial on the same charge, and has pleaded not guilty on the grounds of marital coercion.
She told the court she met Huhne in 1982, a year the break-up of her first marriage, and they married a year later despite her having 'second thoughts' which at one point caused her to break off the engagement.
Pryce already had two children at the time of the wedding, and she went on to have three more with Huhne.
When they met he was a Guardian journalist with political aspirations, though she said she initially opposed his decision to stand for the European Parliament.
His post as an MEP forced her to give up her job as a corporate economist used to international travel and take up a position in the UK.
'I had made it very clear I didn't want him to be an MEP because of what it would mean and I was absolutely right about its impact,' she said. 'There was very little I could do because he was set in his way.'
She testified that Huhne was relentlessly focused on politics, adding: 'He was not around an awful lot and at the time I had my job and children so I had to absolutely rethink my entire life.'
Pryce described how in 2002 he decided to seek nomination as the Lib Dem candidate for Eastleigh, and split his time between campaigning and his work as an MEP.
Claiming that Huhne was keen to avoid losing his licence, she said: 'I knew, of course, immediately that I had not driven the car and, of course, had not incurred the penalty.
'But also I resisted. I had absolutely no wish to take on his points because I knew full well he was a very, very fast driver and very often ignored speed limits and had brought it on himself.'
Pryce said that the couple argued about the issue for a few days, and later she found a letter wrongly naming her as the vehicle's driver.
She testified that she 'exploded' and swore, saying: 'What is going on? I am not doing this, I am not signing anything, these are not my points.'
But a few days later, the court heard, Huhne handed her a pen and said: 'You have absolutely got to sign that. If you don't, the implications will be considerable. It's ridiculous you're not signing it, just sign here.'
She said: 'I looked at this and realised I had absolutely no choice. I was already nominated. It looked like a complete fait accompli for me and for him.
'I had been worn down over a period of time and it looked to me like it was the only thing I could possibly do. It didn't look to me like I had any choice at all in the matter so I took this pen and signed - protesting all the time, but I did it.'
But she said the points swapping remained a bone of contention between them, and she would subsequently bring it up during arguments: 'It really upset me, I thought it was morally repugnant.'
