If it is a matter of SAFETY - then ASK...the worst that they can do is say no. You need to tell them the truth...no exaggerations...if you fear for your safety - then you should have a restraining order placed against him. If not - then you really aren't that afraid...sorry - but if I feared for my life - I would have it noted in the police department....or sheriffs department..
If you are afraid for your safety or think that your "other half" will beat you - then you need to take the kids and go to a W.'s shelter until you are #1 on the list...
If your "other half" is going to be mad because you've not moved up the list faster - that's another problem. You haven't explained how this is a matter of safety...you haven't explained WHY he would upset and not handle it well...so it's hard to answer your question about what I would do...
IF it is a matter of safety - you may have to move in with your mom - no, it's not what you want to do - however, if it means that you AND YOUR CHILD will be safe - then - yeah - you'll have to do it.
