While on Howard Stern's XM radio show early this morning, David Arquette opened up about his sobriety, the future of his dating life and the status of his relationship with estranged wife Courteney Cox.

Arquette and Cox appeared together last night at the 'Scream 4' premiere, but Arquette left early to catch a red eye flight to New York to be in the studio with Stern all week.

With three months of sobriety under his belt, Arquette still says his future with Cox is uncertain. The two were at Disney World recently with their daughter Coco, and Arquette admits they did kiss a little but stayed on different floors in their hotel. However, Cox rejected Arquette when he tried to "make a move on her" while the two were alone.

Cox was recently spotted vacationing with her "Cougar Town" co-star Josh Hopkins, but Arquette insists there is nothing going on between them, and that Cox and he are reaching a decision soon regarding their future as husband and wife.

Does Arquette think the future looks good for him and Cox?

"That's what Id like from her relationship…to have a lot more fun. Some of that stuff is a lot harder for her to do…She can't go to South America and be anonymous there. 'Friends' is everywhere," Arquette said.

Arquette maintains that no matter what, he has Cox's back and that she is "his girl."
