I'll leave you to plan alone (always best), but getting external comments and criticism is necessary in difficult situations. When you can net this down to 5-10 points, ask here again for help.
The kids seem to be reacting realistically (or your pitch is convincing - it's hard to know on my side of this
But if they've taken a position themselves that will be a big help ... because one of your biggest constraints in getting things done is that you shouldn't harm your kids relationship with their father along the way.
In the long run, it's best for them
and for you that they learn to accept (without necessarily understanding) their father's nature. This is why I threw in the "trade-off" line in my previous post.
The science is
very clear: children need both male and female influences as they grow up. Your case is complicated of course, but if it's possible to integrate your ex into their lives as a positive influence, you should.
I suggest you forget about the money-related issues for the moment, except as noted below. For now, start with the hard problem (previous paragraph).
The exception: you said you got less child support last time around, implying it may have been an attempt to influence your behavior. If you have the patience to play a long game, this kind of behavior is advantageous.
Document everything. If you're getting cash rather than bank transfers, deposit what you get, tag it "child support", then get a printout. And take notes. Courts don't like drama, but they
love well-documented patterns of behavior.
PS: Almost all apologies are performative. They're actually a favor from the offended party to the offender, to help them resolve their mental discomfort.
Trying to
force one reverses the natural direction: it's a weird, generally unproductive dominance game.
If your ex is a Narc, he's interpret it as a weakness.
If you want to annoy him, set up a situation where he has no choice, than
ask him politely to do what you need ... but in an absolutely neutral way. Don't signal
anything. Be as nice about it as you can - ideally deliver it as though
you were forced.
He'll never forget it
