Charlie Sheen tries to reconcile with ex-wife

London: Actor Charlie Sheen is reportedly thinking of getting back together with ex-wife Brooke Mueller.

Sheen and Mueller went through a messy divorce in 2009, when she alleged Sheen threatened to kill her.

A source told TMZ.com that the pair have been "getting counselling and therapy (with) the boys" and Mueller, who has struggled with substance addiction, is "actually responding to treatment".

The 45-year-old actor has taken Mueller to Mexico to reward her for how well she was doing in rehab, and also to celebrate her birthday. "She's totally gung-ho," said the source.

"He just wants his kids to be happy, and if that means they need to be a family, then he is up for it... The kids have suffered a lot, and he feels so guilty lately," the source added.
