Is he interested in me at all? - wedding messages on programs

I met a man on the master program is online. He came to the wedding of my brother and stayed for 5 days in the city. Everything that was great between us. He returned to his hometown and not from him until two weeks after hearing of the wedding. Recently, I have a text message to him and has a week to send a text message and call to my home. Sorry to say (or should I fortunately?) I was not at home when I called and it was too late when I saw the text message did not write again. Should I wait until he calls again, or I'll text message or a reminder? Are you interested in me or just "educated"?
Thx!
