She's trying her best to keep things moving in a positive direction.

Jennifer Garner took her three kids to church on Sunday, and she seems to be handling solo parenting like a pro while Ben Affleck works on himself in rehab.

When the Peppermint star intervened and took her ex to a treatment facility last week, a lot of people were hoping that a reconciliation might happen, but the former couple actually just reached a divorce settlement, which will get filed when he completes treatment for his addictions.

They didn't have a prenup, so everything gets split 50/50. They will also share joint custody of their children, assuming the Oscar winner can stay on a healthy path.

We're beginning to learn more about what drove Ben back to the bottle, too.

"Ben had been content in his relationship with Lindsay, but the travel became a lot to deal with. They talked about Lindsay moving to LA but it wasn't going to happen. They tried hard to make it work but with their families on both coasts it was tough to have a consistent relationship. This put a strain on Ben and he started drinking again," a source dished to E! News.

"Ben was doing well for the last few months and very committed to his sobriety. But recently he started to slip up and began drinking again. He wrapped his movie and had some downtime. This week, he was heavily drinking alone at home and with the Playboy model," the source added.

Jen G is a real class act!
