From what I see, your H is losing control so he's taking all kinds of potshots at you in order to beat down your confidence and trying to assert control now that the D train is moving forward. When the LBS files or asserts their parental rights by asking for custody, the WAS gets all hot and bothered when THEY were the ones that wanted out of the M in the first place! Too funny!!
If I were you, I'd want to work with a L to get all of H's financials, access to accounts, and his paychecks so an equitable formula can be caculated for child support & any maintenance. Do you have a Controlled Separation order in place? Or some type of arrangement in place now? Many of the WAses don't like to be parted with their money as they want to spend on themselves and the OW/OM to continue with their fantastyland.
As for the horses, I'd have the L take a look at it as to where the funds came from to purchase these animals as they don't come cheap at all!
Regarding Church, what does it matter if H takes the children to a different one? It is HIS choice. Let him walk on his own path in that direction.
