Should I tell him?

I broke up with my ex a month or so ago and immediately regretted it. I was going through a lot of (unrelated) personal stuff at the time and was overwhelmed and dumped him. I realized my mistake and wanted to get back together, but he wanted time in fear of me doing it again. I didn't respect his wish and begged (pathetic, I know) and he got upset, so I haven't brought it up since. I told him I was over him, and really thought I was, but I guess I'm not. We're still friends but nowhere near as close as before. He has been looking at me, flirting with me, and just being there more than most normal friends would, and I think he still likes me, but he also has a flirty personality, so it's hard to tell. I'm unsure if I should tell him how I feel, because I'll never get him back if he doesn't know, but I don't want to scare him out of my life completely.
