Hi seh77. I am glad you will not be staying in the house with her. Good for you for recognizing that would not be a good decision!
The suicide threats, I believe, are indeed manipulative. I am sure you know the best way to handle that is to call 911 on her behalf. If she is serious, she will get help and if not, perhaps she will learn to stop using one of the most vile manipulation tactics out there. Either way, calling 911 is good for everyone involved. My heart breaks when I think of her daughter being around that.
I always hate it when people bring in these "others" to reinforce their stance or point of view. It leaves one guessing and wondering who is talking about you and watching you. I am 99.9% sure these others do not exist outside of her own mind and she is saying this as another manipulative technique. Again, good for you for responding the way you did! Excellent!

All she keeps talking about is how I haven't changed for her. How I don't do things to show her that I love her.
apparently her idea of love requires you to change who you are to suit her. Everyone defines love a bit differently... .she has shown you at least part of her definition of it. Do you still want it if it requires you to be someone other than the authentic you that you are at this very moment? (I know! That was an awkward sentence!) Does that match your definition of love? Somehow, from reading your post, I think not. It sounds to me like you have a beautiful spirit and your heart is in the right place. Hold on to that.
As for hurting right now... .well, I do not mean this sarcastically at all... .but(!) of course you hurt. It will get better.
I hope you find a safe warm place to call your own.
Take care.
