"Every time his name flashes up my heart races and I have flashbacks to all the times he has terrorised me. I'm still being terrorised and watched and pursued."
Mr and Mrs Eckersley were childhood sweethearts, having met at school when they were 14.
They married in 2005 but split up in August 2015. Eckersley moved out of the £600,000 ($1.14m) family home in Cheshire, and the two sides instructed divorce lawyers.
Giving evidence from behind a screen, Mrs Eckersley, 44, said: "By March 2017, Matthew had received a letter from my solicitor telling him not to contact me other than through solicitors.
"I was to have no contact but the landline kept ringing several times. When I did 1471 [which shows the last number that called] it was his number."
Last August, police warned Eckersley not to contact his estranged wife but he continued sending her emails.
One note relating to maintenance read: "Hi Zoe apologies for this I've just seen it and have made payments. Thanks Matthew". A second said: "Hello Zoe, your car has been insured with Esure - I will send it over on receipt. Thanks, Matthew." A third added: "Please can you take a picture of gas and electric meters and email them over? Thanks, Matthew".
But Mrs Eckersley, who now has a new partner said another message quoted when she had left the house and for how long. When she blocked him on Facebook messenger, he still managed to get the message through, also sending it via email to ensure it was received.
"It made me feel physically sick," she added. "It's so hard to put into words how I feel it's been going on for three years. I don't like receiving any contact it's going against everything I've asked for. It's not respecting my wishes."
In his defence, Eckersley said he was simply trying to save money after a protracted and costly divorce.
"On mundane things I couldn't really understand how I could create myself or Zoe another bill of £300 to go back and forth between the lawyers," he said.
"We are going to go well over £200,000 because of ridiculous things that keep happening and I just can't afford it. There's no need to go to the solicitor to get a meter reading for gas or electric. Even with the car insurance it's a ludicrous and silly thing to have to go through lawyers.
"It's not affordable. It's going to ruin us, it's very upsetting and it's costing a fortune."
He said he had been advised to use private investigators to prove that his wife's partner had moved in with her.
Eckersley was found guilty of harassment without violence and ordered to pay £1500, including £100 compensation to his wife.
