Jennifer Garner and her boyfriend John Miller's relationship seems to be heating up as there have been murmurs of them getting engaged by summer. And their latest romantic date only seemed to fuel the rumor mill.

Garner was recently spotted leaving Miller's home in Los Angeles after what was apparently a romantic evening in. In photos obtained by Daily Mail, Ben Affleck's ex-wife bundled up in a dark jacket, faded denim jeans, dark brown boots and a heavy scarf for the chilly temperature. She was then seen hopping into her car for the drive home.

Garner and Miller, who have reportedly been dating since spring of 2018, have mostly kept their relationship away from the public eye. And this might be because they usually spend their time together indoors.

A source told Entertainment Tonight last month that Miller often comes over to Garner's Pacific Palisades home to spend time with her and her three children, Violet, Seraphina and Samuel, whom she shares with Affleck. They reportedly often stay up late playing board games.

The source also said that things had gotten "serious" between Garner and Miller after spending months getting to know each other. They reportedly "couldn't be happier" that they have found love in each other, but they are in no hurry to tie the knot again after their respective divorces.

However, as her relationship with Miller continues to grow, the source said that the actress is reportedly spending less time with her ex, Affleck, although they still co-parent their children. Garner reportedly wants to focus her attention on what she has going on with Miller.

"Jen is trying to move on and has built a healthy foundation with John," the source said. "They enjoy their time together and that's helped Jen put things into perspective.”

"Jen is at a very healthy point in her life," the insider added. "She adores her kids and her career and has fallen in love with a man who is supportive and loving to both her and the kids.”

Garner and Affleck announced their separation in 2015 after 10 years of marriage. They finalized their divorce on October last year.

Despite claims they are seeing each less frequently, however, Garner and Affleck still meet up on Sundays to attend church service with their children. Just this Sunday, the exes were spotted at church in Pacific Palisades, California, as seen in photos released by Daily Mail.
