Hi, I'd like to help you with your question.
You are in a very difficult position and you have thought this through very well. The main issue here is protecting yourself and your daughter from your ex. Emotional abuse is some of the worst abuse you can suffer because it does not show on the outside. It is used to wear down your self esteem and your sense of self to the point you are completing dominated by the abuser. The danger here is that your ex would lash out because of his lack of control over you and hurt you and/or your daughter physically.
Is there a friend you can stay with now? It may be inconvenient, but getting out now would ensure you do not have to go through the next two weeks anxiously hoping you do not have a confrontation with your ex.
If you cannot go with a friend, how about an extended stay hotel? You could put your things in storage. It is a short term arrangement, but it might be worth a try.
Do you have any male friends or relatives that you could call on short notice in case you have a confrontation with your ex? You need someone with you that could not be overpowered by your ex.
Keep the police and any other emergency numbers on hand in case.
How about contacting a women's shelter to ask about options? They may have contacts for you or offer resources to help. You can also turn to them in case your ex throws you out. It is good to have contacts ahead of time and know where to go just in case.
If you can, send your items, all but the essentials, ahead to your son for storage. Short term storage should be relatively cheap and is worth the hassle.
Once you are settled, it would help if you could see a counselor with your children. From your description of your situation, I would say you have been through a horrible ordeal. All of you could benefit from counseling and support. Here are some resources to help:
I hope this has helped you,
