Tim Galley, 47, was found dead at his home in Wrexham on Tuesday,10 days after developing a fever, according to his girlfriend.

Donna Cuthbert, 46, said she suggested that Galley – her “beloved, best friend and soulmate” – call the NHS 111 line for advice as his temperature rose, but he declined.

He said he had no underlying health problems and that the NHS would be too busy dealing with other people, she said.

“My amazing Tim didn’t want to waste the NHS time so chose not to phone and get help and rather stayed at home in isolation thinking he would get better.”

Public Health England has advised anyone who thinks they have symptoms of the coronavirus – a dry continuous cough or a high temperature – to phone 111 instead of attending a GP, pharmacy or hospital.

In an interview with North Wales Live, Cuthbert paid tribute to Galley as “her future”, adding that he had “a massive heart” and was loved deeply by her children.

She said Galley’s illness started with a small tickle in his throat after going on a stag party on Saturday 14 March. She said he then became unwell and developed a fever three days later.

“Of course I was very worried about when he developed the fever, as I was worried about the coronavirus. But as he wanted to protect me I couldn’t go and visit him,” she said. “As he was getting steadily worse I asked him to phone for an ambulance but he kept on saying to me that he was fine, that he had no underlying health conditions and that they would be too busy dealing with other people.”

She messaged him on Monday night, concerned they would not be able to see each other for at least two weeks because of the UK-wide lockdown. His reply was: “Don’t be silly, of course you will.”

Cuthbert added: “On Tuesday morning I was panicking as Tim didn’t return my calls. I asked his neighbour to check on him as they had a key. They found him in bed.

“Paramedics in protective clothing came, and I just can’t bear the thought he was all alone.”

Cuthbert, who runs a wedding business, urged people to take seriously the government’s instructions to stay at home unless absolutely essential.

In a tribute on Facebook, she wrote: “Tim was my best friend, my world, I’m going to miss you, my heart is broken into shattered pieces and my kids are truly devastated. I really don’t know how we will get through.

“Stay safer everyone. Tim followed the guidelines and took the precautions but still somehow this cruel, cruel virus we think took him. RIP Tim I’ll love you forever.”

Public Health Wales declined to confirm whether Galley had died from the coronavirus, adding: “We do not comment on individual cases, we have a responsibility to protect individuals tested, and patients being treated, for novel coronavirus (Covid-19).”

In its latest update on Thursday afternoon, it said 28 people had died after testing positive for coronavirus in Wales, with six further deaths since Wednesday. There have been 741 confirmed coronavirus cases in Wales to date.
