David Arquette.Despite a public split and some nasty gossip, David Arquette and Courteney Cox are still getting along just fine -- and even had dinner together last night!

David was on "Live! With Regis and Kelly" this morning, where he said "I love my wife, she's an incredible woman, we're just in different places right now. There's gonna be a story coming out that said I was a cheater, but I was faithful to my wife for 11 years."

He says that although they "had an agreement" to see other people, there's "always a chance" they could get back together -- adding that he "loves her with all my heart" and said they had dinner together last night.
