If it were me, and considering you concern about the kids, I think I'd ease my wife into it (or your way out of it) rather than make an all in statement as an atheist and jump right into therapy.
Start off with saying things like "I need to explore, I'm having some doubts and questions, There are things about god/religion that don't feel right any more, ......." and see how that goes, eventually ending up at agnostic/atheist. Don't attend church as much (make excuses as need be), don't get involved in religious discussions, that kind of thing. Maybe she'll be OK with you appearing "christian lite". I'm told these folks are often referred to as the unaffiliated.
She can't be all that devout if she considers divorce a solution. (google Covenant Keepers) Unfortunately, if push comes to shove, divorce may end up being the best solution for you and the kids. It may be bad, but it's not the end of your/their world.
Best of luck.

Being told you're delusional does not necessarily mean you're mental.
