Elin Nordegren is preparing for a bitter custody battle with her cheating husband Tiger over the couple’s two young children.

The ex-model has vowed to bring up Sam, two, and Charlie, 10-months, alone – ­limiting the golf star to occasional visits.

Elin had been prepared to discuss ­amicably joint custody arrangements with Woods, 33.

But she has had a change of heart because of Woods’ refusal to see sex addiction doctors about his appetite for illicit romps.

His stubborn denial of his problem has driven Elin, 29, over the edge and ­prompted her decision to try to limit his involvement in the children’s lives.

One of Elin’s friends told the Sunday Mirror: “She can’t believe Tiger’s behaviour. He says he wants to save the marriage but he’s not doing anything about it.

“He’s hiding out like a child and refusing to go to rehab to get the treatment he needs. She’s so mad at him, she’s flipping out.

“Everyone wants Tiger to get treatment and going down that road was his only real chance of delaying the divorce, but he wouldn’t even sit through therapy
