Jessica Simpson is reportedly growing impatient with boyfriend and Dallas Cowboys quarterback Tony Romo, who still hasn't popped the big question.

"Jessica was really hoping that she was going to get an engagement ring," says a source close to Simpson. "She wanted one for Christmas, then she thought maybe New Year's Eve. Her last hope was that Tony would propose on Valentine's Day--but he didn't."

But she shouldn't have been surprised. As OK! previously reported, Tony seemed distracted during a Feb. 13 dinner with Jess at NYC hotspot Waverly Inn, where he spent 15 minutes texting on his iPhone. "Jessica was not happy," an eyewitness tells OK!, adding that the Dukes of Hazzard star tried desperately to get Tony to focus on her. "He just wasn't picking up on the fact that she was starting to lose her patience."

"You know, I really thought he was going to make it happen this time. I thought he was ready to propose," Jess told Ashlee, according to a friend. "I know Tony loves me, but I don't know if he'll ever propose."

"Ashlee has always been the more realistic, more practical of the two sisters," the insider tells OK!. "And Ashlee knows how much her sister wants to be married and have a baby of her own. But as wonderful as Tony is, he is not the marrying kind--probably not for years." (OK! Magazine)

I can't imagine why Tony Romo would have any hesitation to propose. I mean, it's not like Jessica was married before and had a reality TV show where she made everyone who watched feel sorry for her husband, who seemed like a genuinely nice guy that had to put up with her crap and also constantly complained about never getting any. Why wouldn't an NFL quarterback voluntarily subject himself to that? I just don't get it.
