The 49-year-old, who broke up with his girlfriend of five years Jenny McCarthy back in 2010, has had to 'erase' his former loves and doesn't know if he will ever settle down permanently again.
He said: 'I've been erased and I know what it's like to erase someone. You know the feeling when you loved somebody and it ends and you feel as if they've moved on or maybe even none of it ever mattered? It is a terrible feeling.
'But everything in my life comes to me for a reason, to step me up to another level and to make me learn. Every single relationship I've had has brought me a little bit closer to realising what I want and what I don't want, and teaching me the value of love.'
The Mr. Popper's Penguins star added to British newspaper the Daily Telegraph: 'I don't know if I will ever actually find somebody I can hang with for the rest of my life. I don't regret anybody and I absolutely value whatever it was that took me to where I am now, which is a good place.'
