What did he mean?

this past weekend I hung our with one of my ex-boyfriends. I have not seen him in almost a year. We start small talk and he asks, “so who are you seeing. Now days?” I say no one and he says,“I can’t see you dating anyone” I was a little offended and asked why and he just said,“I’m not trying to be mean I’m just saying.” is he saying that I’m so terrible that no one would ever want to be with me or what? Please be honest.
