Bad nightmare about abuser

It’s 3:12 am and I just woke up from another bad dream with an ex who abused me in it. Now I’m looking around wondering if he’s in my room or my house. I know it sounds crazy but I reached across the bed trying to find my phone and was afraid the he stole my phone and was hiding in my room. The dream was about him coming to my house at around midnight and ringing my doorbell and pacing in the front yard and looking through the windows which he use to do for real. When we was together, I would try to break up with him but instead he’ll choke me until I couldn’t breathe and tell me I wasn’t leaving. So I’ll stay. He almost killed me on his birthday from choking me so hard. As he had his huge hands around my neck choking me and asking me questions at the same time, I couldn’t talk and felt light headed. I finally fought my way to get to loosen a bit, and hoarsely I said, I won’t get an abortion. Then he forced me to perform oral sex on him, having me on my knees until they hurt and turned me around forced rough sex, the same thing he did a month ago but promised me he would never do again. But he was doing it again, and even worse. He apologized and I told him I would stay with him. Then he became depressed after his life situations and I used that time to run away. He called and texted me countless of times, and sent flowers and candy to my house. I ignored it all. Had an abortion which I regret every single day and moved on with life. Now I’m still afraid that he’s out there looking to get me. I fear that one day I’ll be home, and he’ll come kill me. Every place or street that reminds me of him I get anxiety. Every song, memory, food, clothing item. I need therapy. I just want to be over this.
