What does it mean when a guy says "Oh" through a text message?

Anonymous
I know it could mean a lot of different things, but I noticed he has been doing this recently. Like this one time I made a joke about a movie he was watching and he just replied with "Oh" and this other time I got angry with him and he was conversating with me but then I said "Well I am not like other girls" and he replied like 5 hours later with just "Oh" like what does that usually mean? Like I said I know it's hard to tell cause "Oh" could mean a lot of things, but what does it usually mean when guys do it? Is it cause they are interested? Puzzled? Disinterested?
