How do you tell kids their father has left?

I just found out today my husband has been having an affair. When I confronted him about it he packed a bag, left $200, and took off with his other woman. We have an 8 yr old, a 6 yr old, and an 18 month old. How the hell do I explain to my kids their daddy isn't coming back? via /r/Parenting http://ift.tt/2ewYA1g
