Ben Affleck and Jennifer Garner find it "annoying" that they still live together.
The Batman v Superman: Dawn of Justice star divorced from the 13 Going On 30 actress in June but are staying under one roof for the sake of their three children, Violet, 10, Seraphina, 7, and Samuel, 3.
A source told PEOPLE magazine: "It's obvious many times that they both find it annoying to deal with each other. Understandably so. It's a strange situation to live together and yet be separated.
"They both seem to find the situation frustrating, but for now at least, they also seem to think it's best. They are doing what is working for the kids."
Meanwhile, the former couple are said to be putting any "conflicts" to the side to make things easier for their three kids.
