She goes big or she goes home, and she’s not going home.

Vicki Gunvalson spilled some serious tea on her recent breakup with ex-fiancé Steve Lodge, accusing him of infidelity and airing other grievances in a slew of scathing Instagram comments.

“He used me, he lied to me, he’s been dating a 36-year-old and is not what he portrays himself to be. No Christian man would do what he’s done,” the “Real Housewives of Orange County” alum, 59, alleged on Friday under BFF Tamra Judge’s post supporting her.

In another comment, Gunvalson claimed, “While I was out of town working on a biz trip, [Lodge] took [the woman] to my condo in Mexico! He’s been flaunting around my town in OC making out in public places. It’s disgusting.”
