In the event of a breakdown of marriage (separation/divorce), how is child custody split?

[Waheymum]

I'm frustrated with my DH for numerous reasons at the moment, though I'm not sure any of them warranty divorce at the moment. I have options to get out with the kids and always will have realistic options.
No DV (but I'm beginning to suspect emotional abuse from him to me, it can just be difficult to take a situation and define it as definite abuse), no affairs.
The thing is that I don't really trust him to be a good parent if left entirely to his own devices (which he would be, or his unquestionably abusive mother would step in), so I'm wondering how custody of our toddler and baby would likely be split. Any ideas? Is it normally 50/50?

It will depend on a few things. Which country you live in, the ages of the children and the current primary carer.

Would he want them 50/50 do you think?

If he wants 50%, he will get it

Unless problems with drugs or abuse then yes, pretty much 50/50 is the default.

50:50 isn’t the default with very young children - older children yes and to be worked towards
how old are they.
What examples of things make you think he can’t parent ? Because it’s hard to say you’re ok with overnights at weekend etc hes not safe for 50:50 . Is he actually a danger by his actions or just doesn’t parent how you do?

will he even want that ?
