Strange that you write about this. I was just thinking about the best sex I had with my narc ex. It still wasn't great. But it was better..and for a weird reason. We were in conversations over our dissolution, neither of us had ever been with anyone else, I was horny as hell, not ready to date, and was detached enough to ask him (like a favor). It was the most liberating experience of my life to that point. I didn't need him. I didn't want him, really. He was a body. I was treating him, for once, like I had been treated for almost 3 decades. I didn't give a single shit about him for just a little while. It was about me...getting my needs met, for once. It was a very strange experience, but I am so glad I had it. It really helped me to see where I had failed at boundaries before and created no question in my mind as to why leaving him was the only way to really take care of myself, and then my kids. It was finally okay to have something be "about me" and this was my way forward, for some strange reason. I apparently had something to prove to myself. And I did.
