Just so you know, you have the right to apply for a restraining order, yourself. I suggest you do so, and enforce it if she violates it.
You cannot afford to be in any kind of relationship with this woman, not given what has happened and what could happen to your life if she ever were to do something like this again. You should have no contact with her of any kind.
I've worked a long time in the domestic violence field. I am aware that there are "victims" who are not really victims. I believe what you are telling us because you have no reason to lie to a bunch of strangers.
No matter how much she promises to change, I wouldn't trust her after something like this. It is abuse toward you, and abusers tend not to change. They are too dangerous to be involved with.
You are handling it the right way. Get your stuff (with escort), get the restraining order if you can, and do NOT communicate with her in any way. If she calls you threatening suicide, hang up and dial 911. Document everything.
And Al-Anon is a very good idea. It is NOT a religious program, despite the mention of "God". I am an agnostic, myself, and I consider my higher power to be the universe. The truth, which is what it is, regardless what spin I put on it.
