Wow, Melissa, I'm happy to see how calm and composed you sound! It looks like you're legally protected, have kept your cool around your H, are keeping the kids safe and well-informed, and know what you want. GOOD FOR YOU.
Yes, give yourself as much time as you need to talk about the house. Meet at a public place to talk about it (restaurant?)
Keep up the good work, and best wishes to you on Christmas too.
