Hey Daisy,
I love talk radio, and my favorite champion of kids and dads is Dr. Laura. She has her own version of the 3 "A's":
Adultery, Abuse, Addiction.....any one or combination of those 3, renders "wedding vows" null and void. Oh, you can still stay and try to work stuff out, but you are no longer "required" to.
Oh and Pelican's ref to George Burns as God, I can almost literally see and hear him rasp....... "It's O.K." Funny is good. Thanks P!
Thanks and God bless us all,
Coyote
