I've just caught up on the whole thread since I posted yesterday.
I absolutely get why you've pulled back on ending things. I was that soldier.
When I read this thought, my heart sinks:
we have agreed to start out with trying to never, ever, ever argue in front of the kids again.
Without counselling as a couple, with both parties committed, I'm sorry to say, this stands zero chance.
I know you both mean it. Now. But the destructive relationship patterns that are ingrained, are there too long to be able to say, 'oh we'll just stop arguing so'. Logic will go out the window when frustrations rise & anger intrudes.
Also, his treatment of you is shocking. I'm struggling to see any respect from him, or any care for you, his spouse. He seems to blame you entirely, a common scenario.
I'd really really urge you to reconsider. You responded from a moment of clarity when you asked him to leave.
I know his situation is difficult. But he's an adult. He'll have to make his own path, and decide how he wants to be there for his children.
If not, you could try counselling. In fact, counselling to end the marriage some way amicably might be useful.
I wish you luck & strength 💐
