David Arquette doesn't know if he'll marry again.

The 42-year-old actor is "madly in love" with partner Christina McLarty - who is pregnant with his second child - but is hesitant to walk down the aisle because his divorce from Courteney Cox in 2012, almost two years after they separated, left him heartbroken.

"The divorce, that broke my heart a lot, you know, and changed my approach to it all too," he said. When asked on Piers Morgan Live if he will marry again, he added, "I don't know. It has definitely changed that, you know, that experience changed it for me, but you know, I'm madly in love with my new girlfriend and she is a wonderful person and dear friend and we have a kid on the way, so I don't know."

David, who married Courteney in June 2009, also claims his divorce from the Cougar Town actress - with who he has nine-year-old daughter Coco - made him more mature in his relationships: "I was really dramatic and really like over the top when I was younger. But not now, not now. I'm a little more grown up as far as relationships go. I don't - it doesn't seem like everything is the end of the world, you know. When I was younger, I'd get pretty dramatic."
