How do I deal with intrusive thoughts?

I’ve gotten intrusive thoughts about myself before (getting killed violently, etc) that are pretty typical. Recently, I’ve been getting them about my boyfriend. I’ve been thinking that he’s horrible and none of his friends like him, and that he wouldn’t have a girlfriend if not for me. I don’t actually believe this and they’ve only been popping into my head today. I was thinking about ghosting him and laughing when he cries. I feel so awful and want them to get out of my head. Is this normal and how do I get rid of them?
