It depends on exactly what you mean by hard to get. As a game, making a romance happen slowly and making each step take a long time, having fun with the chase?
Yea, that can be fun.
Making it seem like if he doesn't jump through the right hoop he won't get you, ever?
That's emotionally abusive and very unattractive mind-gamey behavior.
And there can be a fine line between the two.
