[Not Quitting]

I am going to tell him that we can have our talk tomorrow (after my counseling session). That will give me a chance to talk it over at my IC, and also give me time to cool down before talking to him.

That sounds like a really good plan. Not only are you giving yourself time to cool down, you're also not giving him a response right away - making him wait until you're ready to talk.

As far as the job goes, you've got to put yourself and your kids first. Would you be able to afford to support yourself with the lower paying job if it came down to it? But at the same time, if your health is going to suffer in the higher paying job that would cause even more problems for both you and the kids. It's not always an easy choice. I'm in a job I love but I really need a higher salary now I'm a single mom (well at least until H decides if he does want to work on our marriage and re-join the family) so I'm currently considering the options as well - and my H isn't aware of any of this because I've chosen not to tell him.
