Any ideas on what this meant?

my ex when we were together told me that i wasn’t his type but my personality was great. does this mean i was an experiment? he stayed with me almost a year after telling me this before he broke up with me due to distance. was this him admitting he isn’t attracted to me or did i change his type? why would he be with me if he didn’t like me? what did this mean?
