I think your email to your H needs to just ask if you guys can find a time talk as you'd like to come to agreement without the added expense and time of lawyers and judges. Negotiation by email doesn't work, IMHO. When you talk live, you can better express the desire to keep the door open while also needing to secure the finances for you and your children. Know where you can flex and where you cannot. It's a negotiation so give and take. Both parties should end equally unhappy, sorry.
