"After seeing tonight's episode I'm pretty hurt," the 33-year-old reality star wrote on Instagram. "I feel disrespected by someone I called a friend and by someone who stated they loved me."
"For five months I was kept in the dark about this. For five months I was naive, probably laughed at and made into a story line that will forever haunt me. My heart hurts on so many levels," she continued. "One thing I learned from tonight's episode is know your value. Don't ever lower your standards."
Additionally, earlier in the episode, Carpinello asked Pivarnick about her sex life, which Pivarnick, 33, discussed on Twitter.
"Why is this kid asking me about my sex life ???? Like why because why ???" she tweeted of Farley's 24-year-old boyfriend.
"There’s a difference between me telling the roomies about my sex life but I didn’t know this kid from Adam," Pivarnick, who is engaged to Chris Larangeira, added in a second tweet. "So, yeah, it’s not cool."
Farley didn't buy Pivarnick's explanation, claiming that she had already told both Carpinello and Lauren Pesce, Mike "The Situation" Sorrentino's wife, about her sex life previously.
"Ummm, you told Zack about your sex life via FaceTime when we were with Lauren’s in Vegas," Farley wrote. "... And also how you can’t stand Chris because he doesn’t pay attention to anything you say ? but I’ll save that for another day Angelina."

The fallout from the incident will air in upcoming Jersey Shore episodes and was teased in the show's mid-season trailer on Thursday. Things seem to escalate quickly, with both women swinging at each other and Farley wielding a glass, while Pivarnick picks up a wine bottle.
