Hi Kepp,

I seem to go through stages with the nightmares. Me and my BPDexh split February - he moved out in April. The bad dreams were frequent then, again in August, again a few weeks ago. They do seem do occur less frequently and over less nights as time passes.
I'm afraid I don't have kids so I can't offer any words of wisdom there.
There are lots of useful threads here about dreams - have a read - it seems to just be our minds way of processing trauma. Many of us experience them. They don't necessarily mean anything. I use a meditation app on my phone to get to sleep when I'm ruminating and it is really helpful for me. It reduces the chance of a bad dream for me at least.
It is hard, but you *are* moving forward. Keep going.
