Make sure you stay busy now, certain days/times will get to you, be self-aware. She is hurting right now so watch your tone and message. Really listen to her beyond the words. She knows she is hurting you and the kids, just because it was her choice doesn't mean you can't show compassion. If you can't muster it up just be still. Make some changes in the house when she leaves, rearrange furniture, move paintings, lamps etc.
