I think Shez is right. Thing is, your kids and your safety is #1, kids especially because they can't get out of there without your help and you are responsible for that. If not for you at all, you need to get your kids out of there. If she's violent enough to injure you with a knife, at what point might she get violent enough to hurt one of the kids, whether accidentally or intentionally? I speak for the kids first and say PLEASE get them out of that situation.

She is clearly not willing to get help or change. Fact is, the red flag is that a counselor actually told her not to come back! When a counselor says that to a client, it speaks volumes about the person that is supposedly trying to get help.

At the very least, if you leave it might put a fire under her butt to get help for real. Doesn't have to be divorce, although if she doesn't want help/doesn't think there is anything she is doing wrong, you should. IMO, you should have full custody of the children and take them out of that mess.

Another thing that speaks to the severity of the problem. Kids, in normal situations, don't easily want to be away from their mom. They cling to the mom and so your child wanting to get away is saying a heck of a lot about the situation.

Do what you have to, get to a friend's, file a restraining order and legal separation.

Again, if not for you, for the kids.

Please post updates.
