(CNN) The estranged husband of missing Connecticut mom Jennifer Dulos said he had a beautiful life before her disappearance, was "enamored" with his girlfriend and that the divorce was the only thing that wasn't positive.

"I would lie to you if I told you that I didn't have a very nice life," Fotis Dulos told NBC's Dateline prior to his arrest last week. "I had a beautiful life, I was with somebody that I was completely enamored with, Michelle. And the divorce was the only thing that wasn't a positive in my life and I couldn't wait for it to be over with."

"But right now my life is a mess and I absolutely had no desire or interest to be in this mess," he said.

The interview also came before the release of an explosive warrant from the Connecticut State Police . Among other details, the warrant said a "bloodlike substance" that contained Jennifer Dulos' DNA was found in the vehicle Fotis Dulos had access to the day she disappeared.
