Breaking his silence following his breakup with fiancée Vienna Giraradi, The Bachelor's Jake Pavelka tells PEOPLE that trouble had been brewing in the relationship for a while, and that there were "a lot of red flags" along the way.
He also denies reports that Girardi was unfaithful, but says there were serious "trust issues" between them.
Still, Pavelka – who broke up with Girardi by phone on Monday from Atlanta, where he was filming a role on the Lifetime series Drop Dead Diva – says that he has not given up the hope of some day finding his soul mate and insists he has "no regrets" about proposing to Girardi, 24.
"I'm still the same guy that believes in love," says Pavelka., 32. "In the end, what I've learned is, it doesn't matter if you love somebody – that doesn't fill 95 percent of the relationship."
