and Samantha Ronson have broken up as many as five times since December, usually after nasty fights, only to reunite amid Lohan's assurances on MySpace that all's well.
So will the latest split
– the first that Lohan has confirmed – be for good?
"It changes every five seconds," a friend of Lohan's tells PEOPLE. "It is up in the air with them. You never know"
The friend, who spoke to Lohan this week, says, "She's in pain and she's alone and feels like the world is against her. She doesn't live an easy life. She has always been in the spotlight. She doesn't know how to live without it but it would be nice if she did for a little."
Lohan's father Michael Lohan, 48, tells PEOPLE his daughter is coping with the breakup by spending time with her mother and sister in Los Angeles. "Dina and Ali are out there with her," says Lohan.
Lindsay, 22, and Ronson, 31, broke up after Lohan was banned from a party Friday hosted by Ronson's sister Charlotte. "We are taking a brief break so I can focus on myself," Lohan told E! news.
Lohan's friend says it won't be easy for either. "I know she loves Samantha and Samantha has loved Lindsay for many more years. From before they even got together – Samantha wanted to have Lindsay in her life," the friend says.
But the friend adds: "Whether [Ronson] is right for her now, I don't know. They both need to be separate for a while. She just needs some space."
