It has been over a year. I was feeling good for the first time in a long time. I had no nightmares. Was sleeping through the night. Had days where I didnt think about him/it at all. Was thinking about future relationships. I was doing so good.

My abuser contacted me twice last week(claimed both were accidental), though the contact was extremely brief- a call followed by an apology text "wrong person" in which I responded "its fine" and then asking me if I wanted to talk the next night(via text) in which I sent a long message saying no and asking him to leave me alone, he of course claimed the text was for someone else. 

Since this incident I feel like I just left him. I've had nightmares on three different nights(though I can't sleep through the night even without the nightmares). Thoughts very intrusively enter my mind multiple times a day, distracts me from my tasks. I can't think of future relationships without thinking of him. I can't even look at guys without thinking they look like him(even if they actually dont). I can't walk down the street without being scared that I'm going to run into him despite being in an entirely different state than he is. 

I just don't know to deal with this. I don't remember how I got past all this the first time, but I do know it took SO long. I wasn't fully healed, I was just getting to the point where I could think about it and try to work things without feeling entirely nauseous. Now I feel neauseous nearly all the time again. 

Does anyone have any experience or advice with recovery regression?
