If what you're doing isn't working...why keep doing it? If what you're doing costs you what you no longer can pay, why do it?
The changes you are talking about making...rings of a real LRT, Last Resort Technique, not a fake one, and it seems like you are at the place of really being able to live up to it.
I made the choice you are talking about, very similar, and while it worked out well for our marriage, there is no gaurentee.
You can even figure out a way where you do not HAVE to talk to her every night aboout the kids, I'll bet.
What you're talking about though...it's all or nothing, and it might take her awhile to realize that. If she does and she regrets it? You've got a hard decision to make if she is sincere.
