is ''very cautious'' about dating anyone.
The True Detective
actor - who has sons James, 11, and Henry, five, from past relationships - is ''reluctant'' to enter a new romance because of the scrutiny he attracts and finds life ''easier'' when he is single.
He said: ''I'm very cautious about entering into relationships. I've basically been single for five years and, even though I love women, it's difficult to get involved and put someone in the spotlight because of my being a celebrity. You're reluctant to expose someone to that unless you're so much in love that you're both willing to put up with the attention that's going to follow you around. Being single is so much easier!''
Colin was previously renowned for his wild partying, and though he admits he had an ''amazing'' time, he was also leading an ''empty'' life.
He told the UK edition of OK!
magazine: ''I arrived in Los Angeles from Dublin and it was a culture shock. I was working non-stop and partying non-stop and I didn't have time to even think about what I was doing with my life. I was caught up in this whirlwind and I had the most amazing time of my life. But it was also the kind of life that leaves you empty a lot of the time.''
