The reality TV star was reportedly unhappy with Waldron's drinking and was also struggling to pay the petrol costs of driving to Warrington to visit him. She is now focusing her attention on her children, according to the News of the World.
She said: "I don't want to be anybody's girlfriend. For the first time in my life I feel like I can stand on my own two feet. I'm staying single. I'm just not in love with Adam - I never was.
"I can't get into a serious relationship yet. Not so soon after Mark. I can't worry about a man. I have to focus on my kids. I've been by myself for the last week and I haven't been able to deal with it. It's made me realise all I want is to spend my summer with my kids. I have missed them so much. I can't be worrying about a man.
"I have to focus on my kids. I'm going to take them away on holiday now. It's the first time I've been able to make a decision like this myself. I decided I just can't split myself in so many ways."
A friend of Waldron's said: "Adam is absolutely gutted. He's been on the phone crying. He can't believe he's let her slip through his fingers. Kerry was smitten with him at first and loved that he wasn't interested in all the celebrity glitz and glamour and was a down to earth, hard-working lad."
