Aaron Rodgers and Shailene Were a 'Mismatch from the Start,' Says Source

Shailene Woodley and Aaron Rodgers' relationship had the odds stacked against it the get-go

"They fell hard and fast, but it was a mismatch from the start," a source close to the exes tells PEOPLE

"Aaron's a complicated guy," the source says. "No one in their circle is surprised this didn't work out

In the bubble of the pandemic, it was easy for them to fall in love and focus only on their relationship but that's not real life."

Earlier Wednesday, another source confirmed to PEOPLE Wednesday that the NFL star, 38, and the actress, 30, had split

just over one year after he made the surprise announcement that they were engaged.
