Melissa Gorga is not a gold digger, despite what Teresa Giudice wants her brother to believe.

On Sunday's episode of The Real Housewives of New Jersey, Gorga, 32, was floored when she learned that her sister-in-law had been trying to poison her marriage to Joe Gorga.

"Joe told me his sister said to him that 'I would leave him for a richer man.' I wish he never told me," Melissa wrote on her Bravo blog. "Why would she ever say something like that?"

"What is she trying to say -- I only love him for the money? Oh, because he's not handsome, charming or sexy? He's not an amazing husband and father? Money is all he has going for him? I don't think so. I have been married for almost eight years now. I have three beautiful children with this man [Antonia, Gino and Joey]."

Melissa -- who once hoped to reconcile with Giudice, 39 -- added that she's "never heard her say anything like this until we joined this show. It's almost like she is planting a seed for everyone to believe. Or even for her brother to believe."

Despite what Giudice insinuated, Melissa isn't worried about the state of her marriage. "It's very clear to everyone what she is trying to do, so I'm not going to get into it that much," she explained. "I think watching me and Joe it's quite obvious how we feel about each other."

Joe confronted his sister about the offensive comment later in the episode, but "she once again had no excuse and said, 'I heard rumors,'" Gorga wrote. "We hear rumors all the time, but don't go to Teresa or her husband and ask if they are true. . . I am his wife and in no way is it right to say something like that to your brother about his wife and expect him to just live with it. If it's just rumors, why put that in your brother's head?"

The Real Housewives of New Jersey airs Sundays at 10 p.m. EST on Bravo.
