It’s been a month since Jennifer Lopez and Marc Anthony announced their separation. But now comes the drama of letting go, especially on the part of Mr. Anthony.

Us Weekly reports that the Grammy-winning singer isn’t quite ready to give up his marriage to J.Lo.

“He calls her non-stop, especially when he’s drinking,” said an inside source. “Marc is constantly harassing her and doesn't think she'll go through with the divorce.”

Marc’s representative denied the phone calls had taken place. On August 10, he and Lopez put on a “united front” so that he could spend time with their three-year-old twins, Max and Emme, in Southampton, New York.

Earlier this month it was reported that Marc was begging Lopez to take him back with a source saying: "His mood shifts from blaming her to begging her to take him back to telling her she is destroying his life.”

The source also said Marc’s behavior, especially while hashing out details of an impending divorce, has been part of a plan. "He's being difficult on every little point...,” the insider said. “He wants to prolong things so she reconsiders.”
