I'm Possessed by My Ex-Husband

I possessed my ex-girlfriend and she didn't know about it. There are many, many things she doesn't know. It's not that I'm hiding it maliciously, it's just that she has abandoned me and is no longer willing to say anything to me. I knew my behavior was sick and looked down upon. But I can't control myself. There are some obsessions and impulses in my heart that drive me to do such a thing. Say I don't have the courage and dignity of a man. Do I care? I don't care. I have been lurking next to her for more than a year, and she still hasn't discovered or realized my existence. It was not easy for me to find her. She looked like bean sprouts in the human world, so fragile that it could be crushed into mud with just a pinch. So I have to take good care of it.
