Getting over someone

The problem here: it was never a real relationship. We were friends who both really really liked each other. We FaceTimed hours every night. Texted all day. He knew more than anyone in my life combined about me. I thought he was the one I’d end up with. A couple months in I finally saw the major red flags and how he was manipulative and had no ambition, so I cut communication off (I’m still friends with his family and close with his sister). I thought I was over him, but I keep thinking and fearing that when I get another relationship I will only think of this guy. Do you girls think I can get over him.
