Daughter and husband separating

Last night, I got a phone call from my daughter.  She said her husband told her he was dome and he gathered some of his stuff and left.  He said he would be back today to get the rest.  They have 3 children 13. 12, and 8.  She is going to cosmotology school, he works on the railroad.  They have been married 15 years.  This really bothers me, being a Minister and Pastor.  Their marriage has been rocky but, I never thought it would come to this.
 
It's about 4:45A here and I couldn't sleep so, I got up.  This is very sad.   I hate it for my grandkids.  They are all great kids and straight A students in school.
