Jonathan Wignall, 54, made the ITV host’s life a living hell after controlling every aspect of her life for almost a decade.
Ruth, 46, is a regular weather present on regional news in London and Wales – and has appeared on Good Morning Britain and This Morning.
Cardiff Crown Court heard her obsessive husband would set an alarm to check her nightly forecasts and had even fitted a tracker under her car.
He would also call her dozens of times a day demanding to know where she was and who she was with.
Last night, the mum-of-two bravely released a statement to her followers on Twitter stating the support she received this week has been “overwhelming”.
She wrote: “I’d just like to say, from the bottom of my heart – thank you.
“I’m overwhelmed by the love and support. I never wanted my story to be public.
Wignall accused Ruth of having an affair – and would demand access to her phone so he could check her messages and delete contacts he didn’t like.
Ruth once woke while sleeping to find music promoter Wignall pressing her fingerprint on her phone so he could gain access, the court heard.
The mum-of-two broke down in tears as she could the court how Wignall had robbed her “of what should have been the happiest times of my life”.
She said: “Because of my television career I have had to try and portray a smiley, happy, sunshine-like personality every day when how I felt was anything but.
“Jonathan’s behaviour has had a big impact on my working life and relationships there have been times in work when I have been unable to keep it together.”
“Living with Jonathan was like constantly walking on eggshells, his temper would turn on an instant and anything could trigger it.”
Ruth decided to leave her husband after 17 years of marriage after he bombarded her with more than 150 phone calls in one day.
After they split, Wignall placed a tracking device under the steering wheel of her car so he could monitor where she was.
The court heard Wignall would also set alarms on his phone for when she was scheduled to present the weather.
He also left a CD in her car containing a recorded message from a psychic telling Ruth the couple would get back together.
Ms Pickthall said Wignall and Ruth had swapped cars before she realised the Fiat he had given her had a tracking device placed on it.
Cardiff Crown Court heard police seized Wignall’s laptop and phone and found an app linked to the tracking device that he accessed more than 250 times in less than three weeks.
Wignall, of Cowbridge, Vale of Glamorgan, admitted controlling and coercive behaviour.
Judge Daniel Williams told Wignall he was a “high risk” to his ex wife.
He said: “She became isolated from her friends and family, you wouldn’t let her travel for work with others.
“You affect the air of a respectable, beleaguered, but successful businessman. You’re not; you’re a fantasist with a fragile ego which makes you an unrepentant, possessive bully.”
Wignall was jailed for three years and handed a restraining order banning him from contacting his wife.
