"Otherwise I might as well stay at home and get lots of cats. No offence to multiple-cat-loving people who stay home, but my greatest fear is loneliness, even though sometimes I crave to be alone. I just want some quiet.
"Some days I want to date, other days I think I just don't want a boyfriend right now."
Minogue noted that the lyrics to her song, A Lifetime to Repair, on her latest album say "I thought I'd settle down, a happy-ever-after princess…" but she added:
"I know for a lot of people that's where they want to end up but, for me, it never was. I guess I thought, 'That's what people do, maybe I'll give it a try.'
"But either it isn't for me or I was with the wrong person. I was swept up in the moment and I'm not afraid to admit that."
Minogue said it had been a relief when she and Sasse, who at 30 is nearly 20 years her junior, decided to end the relationship, admitting how hard it is to let go.
"I sing 'I'm Broken Hearted'. Actually, I was broken," she told the Mail on Sunday's You magazine.
The Australian singer also admitted she would consider having plastic surgery when the time was right and admitted that the pain in her knees made her all too aware of her age.
"I'd be lying if I said I never think about getting older," she said.
"Just today I was looking in a magnifying mirror, putting on mascara, and I said to the guy doing my make-up, I think I need to do something."
Minogue said that one her her idols was Jane Fonda, who had once put her looks down to 80 per cent genetics, ten per cent taking care of yourself and ten per cent a good surgeon.
"So if, and when, the time comes I'll be taking a leaf out of Jane Fonda's book," she said.
On her age, Minogue admitted: "The heels come off as soon as I get home. High heels and walking down stairs - my knees make sure I know about it. They're saying, 'How much longer are we going to be doing this?'
"A lot of people I know are turning 50 and one thing that seems to ring true for all of us is: this is me, I feel better within myself now - I'm turning another corner of who I am.
And a lot of things start to make sense. Things that you can't have known when you were younger."
She expressed frustration with the constant questions about her age, noting that men were not asked such things and were never told they looked too old or too young or were not good enough.
