R+B superstar Usher blames his busy schedule for his turbulent love life.

The Yeah?! singer, who has had a string of unsuccessful relationships, claims he needs to find a woman who accepts his demanding career and doesn't expect the same amount of attention as she would get from a normal boyfriend.

He tells the New York Daily News, "It can get confusing, especially for someone who has the type of schedule I do.

"I have kind of messed up in relationships, simply not being considerate to call.

"But it's so hard. I need someone who understands that I ain't forgot about you. And if you be there for me, I'll be good to you when I get home."
