I am going to ditto Job. This is the time to set boundaries and doing so secures your sanity.
No more coming over unannounced. No more coming in for inspections. Curb side pickup for kids. Do it and do it now. Best thing I ever did and Job helped me toe the line.
He wants a divorce that means you get to run your house your way. And that is that very freeing! It is worth every penny to write in these rules: no more coming over unannounced, curb side pick up, communicate via lawyers, and parallel parenting plan in place. Yours is like mine; he will want to control.
Put boundaries in place and you will secure your future.
Hard as this seems, trust me, you have been handed a gift - the future is yours!
