Patti Stanger is single again.

The "Millionaire Matchmaker" and her boyfriend of three years have split, PEOPLE reports.

The Bravo reality star, 54, started dating mortgage banker David Krause after meeting online in 2012.

A source told the magazine that Stanger is doing "fine" since the split and has been spending a lot of time with former "Real Housewives of New York City" star and best friend Jill Zarin.

The couple had exchanged promise rings after dating for a couple of years but were not engaged.

When Krause first met Stanger, he had know idea who she was. When fans approached her on their second date, he was confused.

"What is going on here, this is the oddest thing," he told PEOPLE last year. "But I didn't ask any questions, because I figured she'd let me know when she was ready. And that night I raced home and Googled [her]."
