Jennifer Garner and her boyfriend John Miller are happy and in love with each other. Things between the couple have apparently "gotten serious" and have been enjoying a lot of family bonding moments with their respective children.

A source recently told Entertaiment Tonight that Garner and her businessman boyfriend often spend time together with their kids from their previous marriages. Garner has three kids with ex-husband Ben Affleck; Violet, Seraphina and Samuel. Meanwhile, Miller shares two children with ex-wife Caroline Campbell.

According to the source, Garner and Miller's relationship is going strong and "only continues to grow." The couple reportedly wanted to "take it slow," but things have gotten serious between them. Miller has reportedly been a constant presence at Garner's Palisades home, and the couple and their kids often play board games late into the night.

Despite how well their relationship is going, however, the insider claimed that Garner and Miller are not yet ready to the tie the knot for the second time.

"[Garner and Miller are] in a true honeymoon phase in their relationship and while they've spoken about a future together, neither of them are ready to plan a wedding or get engaged," the insider told the outlet. "Jen has no interest in jumping into marriage quickly. She only just solidified her divorce so right now she just loves all their time together.”

Garner finalized her divorce from Affleck in October 2018. They first announced their separation in 2015 after almost 10 years of marriage.

This news comes after Star magazine put out a story claiming Affleck has been a "wreck" since Garner started dating Miller. The now-debunked report claimed that Affleck had "fallen into a deep funk" and had been "shutting himself off," making his pals worry about him.

However, another source told People magazine the opposite. Affleck apparently wants "the best" for his ex-wife and has no problems with her new relationship.

An E! News report also supported this, with an insider saying that Affleck is happy when Garner is also happy.
