The X Factor runner-up, who previously dated One Direction's Zayn Malik, revealed that she usually falls in love "at the drop of a hat".
"I am a bit done with men, for now anyway. I am yet to find one faithful. I don't know why boys are like that. I think I am too nice with them and let them get away with murder," Ferguson told The Mirror.
"It is heartbreaking to feel that I have been let down like that. But you know what? I have written a bloody good album on the back of it. I have been in love loads. I'm terrible for it. I fall in love at the drop of a hat."
Speaking of her relationship with Malik, she added: "I was with him for three months and people put so much focus on it because we were in the public eye.
"I was 24 then and I'd had two kids and other relationships so remember I'd had a lot of life experience before that. He's a footnote in my life maybe."
On her newfound fame, Ferguson explained: "Before you have money, you want money, and when you have money, everybody wants your money.
"There became an attitude of expectation because I was so giving. I felt I was being asked to pay for things that I shouldn't have to and I am nobody's cash machine."
