David Arquette admits he acted in a "childish" way

The `Scream 4` actor partied hard and admitted sleeping with a cocktail waitress shortly after agreeing to a trial separation from his wife last October, but has since undergone four weeks of rehab for alcoholism and admitted he handled the situation badly.

He told People: "I went through a really hard time, and my way of dealing with it was just to blow it all up. I did act childish, but at the same time I had to - I was really hurt. It was hard for me to deal with this, but what I had to do ultimately was step back and take a look at myself."

David, 39, and 46-year-old Courteney - who have a daughter Coco, six, together - have maintained a good relationship since they started their trial separation, but she has revealed one of their main problems is his high sex drive.

Referring to David`s recent confession that he hit on her during a trip to Disney World, she said: "It was early in the morning. This is one of our problems in our relationship. Whenever I would need consoling from David, he could not literally put his arm around me for one second without completely getting a boner

"So [Disney World] just wasn`t the right time and I don`t want to confuse the issue. We`re going through a hard time."

David has now been sober for over 100 days and is addressing his issues, in a bid to get his marriage back on track.

He said: "I`m really getting in touch with my feelings, and trying to process them in a more appropriate way. It`s easy to numb them, but it`s more fulfilling to feel them. I don`t have a desire to drink.

"My big deal is me starting to look at who I really am. I was living up to ideals that weren`t necessarily who I am. What am I good with? What makes sense for me? Where`s my true voice? I`m still learning."

David and Courteney both star in horror sequel `Scream 4`, which is in cinemas now.
