Radar Online is reporting that things are deteriorating between Tiger Woods and Elin Nordegren, and it's because of Tiger's decision to return to golf.

"There's a reason why Elin didn't go to the tournament and it's simple," the source told RadarOnline.com exclusively. "She thinks he's breaking his promise to her by returning to golf so soon. And as every day goes by she gets a little angrier."

The couple fought about his golf return a few weeks ago when he first told Elin, the source revealed. "And since then she has been ice cold to him," the source said.

"Not only did she refuse his request to go to the tournament but she also has moved away from him emotionally."

Apparently, things were at their best between the couple (since the whole cheating scandal started) about a month ago, when Elin gave Tiger a hug outdoors and he kissed her on the cheek.

"That was when things peaked," said the source, who sees them on a regular basis.

"Elin thinks if Tiger rushed his golf comeback then all he was interested in was getting back to where he was and she doesn't want to go back to where they were," the source said.

"There were so many other women, so many years of betrayal, of Tiger living a lie. Elin has to learn to trust him again and that is not happening.

"In fact, his return to golf has made her trust him less."

Tiger reportedly is "very upset" about this. And it can't be helping matter that women are STILL coming forward, like yesterday, when it got out that Tiger slept with a neighbor's daughter.

As far as I'm concerned, Tiger doesn't have ANY leeway. He should do whatever Elin wants. It's not like he needs to return to golf for financial reasons.
