Stop talking to him. He'll say something eventually. :)
by stepping back
So be it. Maybe that's how he wants it. Just enjoy the quiet time.
cut your tongue
Stop talking :)
Talk about things he's interested in.
Find something you're both interested in, then.
Ask him questions, bring up things he's interested in.
So you want him to ask you questions and stuff? In a playful way say ''okay now you ask me a question!'' w/ a smile and a giggle, he'll get the picture and every time he ''falls'' off say ''your turn!'' :)
Good luck with that because unfortunately I married one of those!!
