I just found out my abusive father is trying to reconnect

My biological father was extremely emotionally and verbally abusive, my mom left him when I was twelve and he finally stopped trying to see and contact my siblings and I when I was sixteen. I hate him I hate him so much and he lives with his mom and she’s just as bad as he is, they’re both clinical narcissists, they’re insane and I hate them. My self esteem was so fucking ruined from their abuse, I’ve struggled with debilitating anxiety and depression that only started to get better after years of therapy and I’m doing alright now but it’s been so hard.

After I didn’t have to see him anymore I went hardcore no contact with both of them and I hadn’t ever felt better, I’m just trying to cut them out of my life as completely as possible and move on so they’re not part of my life in any way, shape, or form, and hopefully I won’t remember them much if at all someday.

I’m twenty one now, I did graduate high school and I got licensed in my chosen profession, and I’ve moved from my childhood home (which he knew the address of).

I found out today, my maternal grandpa told me that my biological father’s mom reached out to him recently to ask about us (my siblings and I) and how we’re doing, he just responded kindly and sent her a couple pictures and told her about how I’d graduated, gotten my license, and the new city I’m living in now. I don’t blame my grandpa and I’m not upset with him or anything because he didn’t realize I didn’t want them to know anything and I asked him not to tell her any more about me at all, he genuinely didn’t realize how much it meant to me.

But I’m really really anxious now that I know she knows what I look like now and where I live. I don’t think they’ll come after me or try to contact me or anything (though I wouldn’t put it past them to try) but i just felt safer, comforted, and satisfied that they didn’t know where I was or what I was doing and now they do and it’s just really upset me.

I hate knowing that now they know. Since I went no contact and they didn’t know where I lived or what I did, I felt like my life was mine again, but now that they’re aware I feel like it makes them part of my life again and I hate it so much:( I’ve been so anxious and haven’t been able to stop thinking about it

(I did take a break from therapy recently but because of other personal reasons I’m starting back up, so I will definitely be processing this with my therapist)
