Find out his hobbies before dumping him. He may be useful as a friend. Get good at chess; there is nothing more humiliating for a man than to be beaten intellectually by a beautiful woman. You’ll be able to cause him physical pain. If he doesn’t let you know how he’s feeling, call him late. Wake him up. It’s hard for him to hide his feelings when he’s in love with you and you’re speaking softly to him in bed, even if it is only on the phone.
