Jake Pavelka's ex-girlfriend Christina Haney tells that he may have raised his voice at Vienna Girardi during their ugly reunion interview Monday, but he was nothing but a gentleman when they dated.

"I feel so bad for Jake," she tells Us.

In the five years that she's known him and the three years that they've lived together, Haney says she's never seen Pavelka, 32, act the way he did during the July 5 interview.

She tells Us Pavelka, 32, "thought people would understand why he got so upset with Vienna during the interview. She always interrupted him and never let him answer a question. Anyone would have gotten mad."

Haney says the show was "edited" to make him "look like a jerk" -- and Girardi, a 24-year-old former Hooters waitress, was good "with the tears and will get a lot of sympathy votes for that."

Haney just wishes Pavelka was able to defend himself more.

He just "didn't want to bash" Girardi, says Haney. "Jake still believes that people will figure out that she is bending the truth."

Pavelka is "upset" over the Girardi split, Haney tells Us. "She was so supportive of him at the beginning, but I guess she wanted some media attention too. I don't know Vienna personally, so I am not going to judge her, but I do remember how none of the girls on the show liked her, and apparently, her hometown has turned against her too. There has to be a reason for that."

As for Pavelka admitting that he withheld sex during his relationship with Girardi, Haney tells Us, "We never had intimacy issues -- ever. He really is a great guy who has just had some bad luck lately in choosing women."
