Ex reached out

My narc ex reached out to me. He put me through hell and back... he cheated, gaslighted me and lied constantly. And has the nerve to ask what he did wrong lol. Anyways, I’m in a very happy relationship now with a man I’m totally in love with who adores me so why does my ex reaching out bother me?? I keep thinking about it. I’m over him but I don’t think I’m over the trauma. But I feel guilty like I still care? I’m not telling my boyfriend he reached out. Is it normal I feel this way?
