The model-and-actress was left devastated when she discovered the 'Snow white and the Huntsman' director had been having an affair with his lead star Kristen Stewart but despite her pain she is keen to try again.

Although Liberty - who has two children, Sykla, seven, and Tennyson, five, with Rupert - has already seen a lawyer, sources say she has no plans to divorce.

According to gossip website TMZ.com, Liberty and Rupert have already been to a marriage and family therapist to try and salvage their union.

However, Liberty - who played Kristen's on screen mother in 'Snow White and the Huntsman' - wants to know why Rupert cheated and needs assurances from him it won't happen again.

It had been claimed that Rupert feared Liberty would leave him for good following the revelations.

An insider said: "Rupert is willing to do absolutely anything and everything he can to save his marriage, he realises this is the worst mistake of his life, and he cannot believe he was so stupid.

"The thought of losing his wife and children, who he loves more than anything in the world is killing him."

Following the cheating revelations, Kristen, 22, issued a public statement apologising for her actions and insisted she did not want to lose her boyfriend Robert Pattinson.
