Hello, I am looking for advice for an annoying compulsion. It started recently, my OCD began pushing me to say my ex-partners name, when I’m with my partner (all though it also makes me want to misname other people). I find it very difficult to manage, primarily because it always feels like I’m going to say it, and I am terrified that it will eventually happen. My girlfriend knows about this, but I know that it would still be a very upsetting experience for her, and I don’t want to make her feel uncomfortable or sad. What do I do? Are there any mind strategies I could use?
