Imagine the following conversation.
A: Oh, there is Bugs Bunny on television.
B: Who is Bugs Bunny? Is it your new boyfriend?
A: I don't have a new boyfriend; I prefer my old boyfriend.
B just wants to know of whom A is speaking; maybe Bugs Bunny is the nick used for a celebrity or for a person A knows, not to mean that Bugs Bunny.
Is prefer correct, in this case? Looking at the definition given from the dictionary, I read the following.
to like one thing or person better than another; to choose one thing rather than something else because you like it better
In this case, there isn't a second person for which the comparison can be done. I would think that "I like my old boyfriend." is a better phrase.
Is it really so, or is there any reason to use prefer in this context?
Should I understand "I prefer my old boyfriend." as "I prefer still having my old boyfriend than not having a boyfriend."? Is prefer really used with that meaning?
