After spending some quality one-on-one time in Montana, the duo parted ways.
Affleck headed to his $20 million Los Angeles mansion and was the victim of a scary home intruder on Tuesday. J Lo flew back to Miami and went straight to her ex, Alex Rodriguez's gym.
According to PEOPLE, "[Jennifer] is in touch with Ben every day," and they are planning to meet up again soon.
"They are making plans to see each other," the source says. "Jennifer is still very excited about how things are going with Ben."
As Radar reported, J Lo looked concerned and was photographed clutching her phone outside of the gym on Wednesday as news broke that Affleck's trespasser was still on the loose.
While police told Radar they are still searching for the suspect -- who they believe is a black male -- the Love Don't Cost a Thing singer's ex-Yankee fiancé is cooking up a plan with his PR team.
Sources reveal, A-Rod is "angry and embarrassed" for how quickly J Lo moved on with Affleck, and he's prepared to play the rebound game.
Radar has learned the ex-MLB star's team is scrambling to find a "younger" woman to replace J Lo on his arm in an attempt to save face.
An insider told pop culture site Deuxmoi to "expect a potential leak to the press from his camp in the next week."
Meanwhile, A-Rod is playing the single dad card.
Days ago, he collected attention when he went on a date with his daughters -- Natasha, 16, and Ella, 13 -- and last night, he showed them all sitting down for a homecooked meal.
A-Rod was seen smiling while serving his teenagers enough food to feed an army.
Fans quickly poked fun at the photo after they noticed there were a few empty chairs, which J Lo and her family used to occupy.
J Lo and A-Rod ended their engagement in April, but several reports claim she's been allegedly sending flirty emails to Affleck since February.
