"Some people miss their partner or are uncertain why they broke up or they feel the relationship has improved," she says."It may be a combination of factors such as continued attachment to the previous partner, less closure if the reason for the breakup was not very clear, or constraints, such as having a child together or living together." As for the "let's be friends" approach, Vennum says there needs to be more research done to see whether friendship with an ex is a feasible alternative. it would probably be less risky if the break-up is mutual and there is clarity on the status of the relationship post-breakup," she says.Or, for those of us who simply love to see our favorite celebrities and soap opera characters play round after round of relationship ping pong.

And in July 2014, they both decided to adopt a ginger-and-white kitten (one Ozzy, one Butter) at the Petaluma Animal Shelter, all without ever meeting. "It was love at first sight," Cavin told Love Meow.

"The date never ended and I went to his house later that night, and I could not believe my eyes. ” He thought I was a crazy cat lady until I had him come over to my house and see Ozzy." The next day, Brian did just that.

A couple of years ago, Melissa Braverman broke up with the guy she'd been dating for six months, then had second thoughts and begged him to take her back.

He did -- which is when the trouble really started.

"On average, partners who were cyclical while dating enter marriage in a slightly more challenging spot than their non-cyclical partners," says Vennum.

"[They] report more uncertainty about whether getting married is the best decision and begin the marriage with more destructive conflict, less feelings of closeness to their partner and lower satisfaction." Vennum says in the world of romance research, there are plenty of theories as to why we continually try to rekindle old flames, even though we may know better.

As for Braverman, who blogs about dating at Single Gal NYC, she says she's sworn off recycled love affairs for now.

"You can revisit but it doesn't mean the outcome is going to be any different," she says.

Their brief romance fizzled out shortly after, but last Thursday the pair were reunited on... Howard and Brigette, now a divorced mother-of-three, had been going home after their respective nights out when they clocked each other.

Howard has since taken to Twitter to share a video of their reunion, writing: "You won't believe this!

Among their problems, these couples reported less communication, greater disillusionment and lower satisfaction and commitment. "Cyclical partners tend to report less conscious decision-making in their relationships; there's more 'sliding,' the term we use for moving through relationship transitions without fully considering the implications," says Vennum.
