There's good reason to suspect the couple could reunite: Multiple sources say that Lohan spent Tuesday night an her ex's Los Angeles home. Meanwhile, Lohan herself told E! News Tuesday that she and Ronson are "in touch" and remain friends. Also, while Lohan was in Hawaii and Ronson was in New York City recently, Lohan briefly changed her blackberry messenger name to "LL loves Sam Ronson."
One source close to the couple tells PEOPLE, "Sam might eventually take Lindsay back ... It wouldn't surprise anyone."
A friend of Lohan's says this breakup could be like other times in the past. "It's a cycle that can go on forever. Now that things have died down a little and Lindsay is behaving herself and showing Sam what she wants to see, Sam's strength to stay away eases up."
However, one friend tells PEOPLE that Sam has "no plans to take her back."
Another source close to Ronson says a reconciliation won't happen without serious repercussions. "Sam's family will literally lose all respect if she goes back to Lindsay, and that's what's convincing her things are really over," says the source.
"They do text, [blackberry messanger], have visits," continues the source. "Lindsay plays stupid mind games saying she is being pursued by major celebrity actors. She has a lot of free time to play all these childish games."
But Ronson is still torn, adds the source: "Sam knows in her head, life is truly better off without Lindsay – even if her heart sometimes says otherwise."
