1. Do your homework and pick out a good MC. There are some posts on that subject here on SSM.
2. Make an appointment, and do your best to make it during a time when she is available. Take responsibility to have the children cared for, so she can't just say, 'but I have to watch the kids.'
3. Tell her about the appointment. Be prepared to dodge the sh!t.
4. No matter what she says, go to the appointment. Yes, even if you go alone.
5. Repeat steps 2,3,4.
