I don’t know what to do

I have been in an abusive relationship for years. We’ve almost been married for 20 years. Together for 25. I’ve just recently admitted to others that he’s emotionally, verbally and has been physically abusive in the past. He’s kept me up at night to argue with me, threatened suicide, hit me, intimidated me and just so much more. I don’t know how to describe it. There’s just too much. I am having like serious physical symptoms now. My back spasms constantly. I have anxiety attacks when I have to tell him stuff I think is going to set him off. My heart feels like it’s going to explode constantly. I’ve started the process of coming to terms with everything that’s happened and finally formulating an exit plan. I’ve been saving money. I’ve finally told people what’s going on and talking to a therapist. Here’s the problem…. He’s been working on things. He’s been ok for a little while now. I’m seriously questioning what I’m doing. I have a daughter who loves him to death and I don’t want to take him away from her. I also don’t want to not see her every day. I don’t know what to do. Please let me know what you think.
