There are no set rules in the game of love, and it’s easy to question if you’re dating Mr. Right or Mr. Right Now. Such doubt often leads to broken hearts, but as many Hollywood pairs have proven, time apart may be just what the doctor ordered during the search for happily ever after. Here are five celebrity couples that reunited after a breakup and found lasting love (for now at least):

Katy Perry and John Mayer: This musically-talented twosome is keeping us all guessing! The couple was first seen together during the summer of 2012; they split briefly in August and then reunited, even spending the holidays together. However, in March 2013, they broke up again. Addressing the split, Mayer reportedly said, “I’m on the same journey as everyone else. Coupling is a tricky thing.” Even so, as recently as June 2013, they were seen together with pals at Chateau Marmont in West Hollywood.

Jessica Biel and Justin Timberlake: Biel and Timberlake first dated for over four years (a lifetime in Hollywood!) before splitting in March 2011. However, they were together again by fall, and in December, Timberlake proposed in the mountains of Jackson Hole, Wyoming. The star-powered duo married in a top-secret ceremony in Italy on October 19, 2012.

Kristin Cavallari and Jay Cutler: This Chicago-based pair first began dating in fall 2010 and confirmed their engagement in April 2011. However, the Chicago Bears quarterback called things off just a few months later. The couple reunited in November 2011 and announced the Laguna Beach star’s pregnancy in January 2012. They took the next step in their relationship, tying the knot in Nashville on June 7, 2013.

Selena Gomez and Justin Bieber: It’s hard to know if these two songbirds are on-again or off-again. The twosome split in November 2012, but always stayed in touch. In April 2013, they confirmed their renewed relationship when the Spring Breakers actress flew to Norway to be with her ex-beau. Keeping the romance alive, the couple appears to be going strong at the start of summer.

Pink and Carey Hart: Pop singer Pink proposed to motocross racer Hart in June 2005, and the couple married soon after in Costa Rica. After two years of marriage, the couple separated in February 2008. However, they remained friends — Hart even appeared in Pink’s video for her song “So What!” — and sought marriage counseling in hopes of reconciling. They reunited two years later, and the tattooed twosome have been happily together ever since.
