Jennifer Garner and boyfriend John Miller are rarely spotted in public together, leading some to speculate whether or not the two are still together. However, there is a reason why the actress and her businessman beau are keeping their romance away from the spotlight.

Garner and her boyfriend were last photographed together in public two months ago, after the couple was spotted enjoying a breakfast date at Brentwood Country Mart. Since then, the "Alias" alum and Miller have not been seen together publicly.

A source told Entertainment Tonight around that time that five months after news broke of them dating, Garner and Miller "slowed things down" and reflected on their relationship. The two apparently chose to focus on other things aside from their romance at the time, such as their children, careers and pals.

However, the "Love, Simon" star and her boyfriend reportedly decided to stay together and realized that "they wanted to spend more time together," the insider dished.

Despite speculations that the two may have split, the source confirmed that Garner and Miller are back on track when it comes to their relationship. In fact, the actress is apparently eager to find out if her boyfriend is "the one."

"Jen wants to continue to explore their relationship and see if John is the right one for her," the source said.

In addition, prior to their May sighting, it also took months before Garner and Miller had been spotted in public together again. Previously, they were photographed enjoying a dinner date with two other couples back in February.

Another source previously told E! News that Garner adores Miller but isn't considering jumping into another marriage after finalizing her divorce from Ben Affleck last year. But the source added that the actress is "determined" to keep her relationship with Miller "private and for themselves" after her highly publicized romance and split from her ex-husband.

"Jen is very happy with John but she isn't getting too far ahead of herself," the insider said. "She just finalized her divorce and finally has closure on a very emotionally draining period of time."

But while they may rarely be photographed on dates, an insider previously told ETOnline that Miller often comes over to Garner's Pacific Palisades home to spend time with her and her three children, whom she shares with Affleck.

"John's been at their Palisades house so much lately," the source said. "They all [John, Jen and their kids] stay up late playing board games."
