1. She has nowhere to go. Should I help her find an apartment or have the OM come get her?
2. My wife takes care of our two daughters ages 7 and 3 during the day while I am at work. I can't afford childcare. Should I have her come get the kids every morning before I leave for work? If she doesn't show up some morning, it would cause me to be late for work, but I could get a backup plan. There are church friends who would be willing to babysit occasionally.
First of all, GOOD JOB on learning your legal rights!
Ken, you need to have ALL of this planned out by the time you confront your wife. This needs to be a "I have learned that ________ , and this is what I've decided: __________________" meeting. Calm, confident, not a debate -- you are INFORMING her of what's going to happen.
You need to have every duck in a row. "I've made arrangements for X," and "I've already covered that with Y" -- that sort of thing.
Are you good at making detailed plans? It sounds like you are.
