Brad tells Details Magazine that he still has a "deep friendship" with Jen.

"Jen and I still maintain a deep friendship and have a lot of life together that isn't erased in any way,"

He also said about the separation:

"I don't know how better to have handled it.

"My view was, this is no one's business in the end - at least in matters of the heart.

"So you need to protect all involved as much as possible.

"I don't know if that cooled things off or exacerbated them, but it was a thing I felt justly about at the time.

"Again, the thing guiding me then was you don't know how many days you have and you need life to be everything you want it to be."
