The former Celebrity Big Brother housemate, who dated Crimewatch presenter Wilding for six months before they were spotted having a public argument last week, said that she has found their split very "painful".
Houghton told The Mirror: "You give six months of your life to someone - you don't expect this treatment. Everyone could see it was aggressive. I've had such a horrible week - it's been the toughest of my life.
"For a girl, especially, it's been horrible. No girl wants to go through this. I find it really painful to talk about. I'm hurt - and I don't feel good at the moment."
Onlookers say that 33-year-old Wilding dragged Houghton across the grass in Richmond park where they had been having a picnic. One said that the TV host was "flipping out" and that Houghton looked "terrified".
He later wrote on his Twitter page: "Sadly Chantelle & I are no longer in a relationship as I've had to draw a line under it. The relationship wasn't what I wanted so badly and wasn't the genuine thing I thought it was. It's so upsetting as I genuinely & truly loved Chantelle, but the publicity side isn't always reflective of the truth ".
Wilding has reportedly been advised by his bosses at the BBC to take a holiday.
