She means what she says, perhaps she is bored doing the same things.
Take a break from the usual expectations.
In other words be independent of her personally.
just do your thing without needing her, she may be taking you for granted.
that may make her come around seeing that.
Take care of the children try not to argue in front of them, this situation must not affect them.Things as usual for them, take them out, let them have fun with you.
Just you and the kids unless she wants to come too.

Take one day at a time,
I wish you well and dont worry about the outcome.
