Is it true that "Guys want what they can't have?" Does this apply after a breakup?

Do you think this is true in a situation whereas the two have broken up and the girl had stayed away from him?I already know that some guys choose to call their exes just because they want sex or because they haven't met another girl. But I'm not talking about that.

Do you think it is possible for a guy to genuinely miss their ex and want to see her and be with her?
