Is this an eating disorder

I was bulimic all throughout high school and college until midway of junior year, which was 2 years ago. I mostly have been purge free every blue moon I do it, but thats maybe 6 six months. Anyway, my friend said she concerned for me because she doesn't think it ever truly went away. She said it's because I only eat once a day and workout for 2 hours. I am still eating though and not purging. Would you consider this behavior an eating disorder?
