Am I asking too much?

I’ve been seeing this girl for two months now, we’re in that stage of more than friends but less than a relationship and not exclusive but anyways, we’ve had the discussion of her disappearing mid conversation for hours at a time without saying anything before and I just see it as disrespectful. Am I asking too much to just be told that she’ll be back later to continue or no?
