I want to call this guy I met a few days ago. We went on a date and the day after our date I texted him to let him know I was thinking of him. He called me that night. But I haven't heard from him all day today. I sent him a text to see how he was doing, but he did not reply. If I don't call him I don't want him to think I'm not interested in him, but he is not calling me, so I think he's not interested. Its like playing hard to get on both side. What should I do?
