I have my own hobbies and interests. My point is that men who play video games for 16 hours a day or watch sports during all of their free time are married to their interests and don't have time for a relationship (unless you two share those interests and are okay spending those countless hours together). I can set down my hobbies in order to have time to build a relationship. If he can't, then I don't have time for him.
