Don’t want to be outed so have changed some details and not going to be very specific, I had a very abusive relationship when I was younger and my now partner knows about the abuse. Never told him his name or anything just that he was awful and left some emotional issues that have lasted my life ever since. Skip to now (been with my dp 15 years) and he has started seeing a professional who turns out to be my abusivr ex. He even had the cheek to ask if he knew me ( don’t know how he knows what my partner looks like as never seen him since) so odviously he had looked on my sm. my sm is private btw so he must have done some serious snooping. This has freaked me out and I lied to my partner saying I didn’t know him. I don’t know what to do. I’m embarised I even had anything to do with him and now my partner is going to have regular contact with him ( again can’t say why as too outing) I don’t know what my partner would do if I told him, if he would hit him ( he did some awful things to me that my partner knows about and he would always say he felt like killing him for hurting me) or be disappointed I lied to him. He could change the professional and not see my ex which I think he would do but I don’t know how to start the conversation with him. It’s brough back a lot of anxiety and trauma my partner even mentioning his name to me asking if I knew him 😢. Advice please
