You're still operating from the standpoint that she's given up. That's a problem. (Hey, one I'm well familiar with because I did the same thing). You need to be operating from the standpoint that you have not given up. This is over when you say it's over and not a second sooner. She doesn't have the first clue what she wants. If she did, this would be way done already. But it isn't. So stop thinking about her giving up.
You know all the time you hear stories of triumph. Those poor miners that were trapped underground for months was a great one. Always in circumstances like that, a hero emerges. In that case, it was the last guy out. We heard story after story of fights breaking out, people breaking down, getting sick and giving up. But that last guy? Well, he rallied the troops, came up with work schedules, came up with sleep schedules, came up with a set of rules. He wouldn't let the others give up. Was he mad because the others wanted to give up? Maybe. But that wasn't his focus. His focus was to get these people out of the hole they were in. And he did. Well, my friend, consider yourself "the last guy." Get your family out of this hole. Forget about her giving up. What are you going to do to rally the troops????
I'm praying for you, sweetie!!! Hang in there. You really are doing better than you think you are.
