Star magazine claims the couple is fighting over Marc’s not wanting to have a family.

Everything appeared to be rosy between Chelsea and Marc at the amfAR gala in New York just last night, but sources claim — shockingly, given the romance of their wedding — that Marc thinks marriage was a “mistake.” And that’s just the beginning.

“Marc pretty much told her he does not see kids in his future,” a source tells Star. “Chelsea was absolutely crushed; she’s dying to be a mom. But it’s just too much responsibility for him. He can’t even handle being married, so how the heck is he going to handle being a father.”

Sources reveal that the reason Marc quit his job as an investment banker and moved to the well known ski town was because he felt the marriage was a huge mistake.

“[Marc told Chelsea] He wanted to regain his freedom,” a source tells Star. “Marc struggled to explain that he made a mistake getting married because he simply wasn’t ready. He told her there was too much pressure. Then he left for the slopes.”

Even though Chelsea has visited Marc in Jackson Hole, a source says it wasn’t friendly. Marc reportedly never picks up Chelsea’s phone calls, and when he does … he says nothing, so she flew out there to confront him.

“It basically ended in a screaming match,” a source says of Chelsea’s visit. “Chelsea left feeling very much alone and brokenhearted.”

But keep in mind, Chelsea and Marc were spotted at a spin class on Feb. 5, and eating lunch at Fig & Olive later that day, not including their united front at the amFar gala last night.
