Capricorn men: suddenly ignoring me and stop texting?

He asked me how everything was going and I replied telling him everything was fine and then I asked him how his day was. He saw the text but didn't reply for three days. The third day I wrote that I miss him. Then AGAIN, he saw the message but didn't reply. Now non of us is texting each other. I find it funny since he blew me kisses, hugged me tightly while telling me how much he was gonna miss me and told me to keep in touch when he left. Then I saw how he shed a tear when no one was supposed to see him. I'm so angry and frustrated, did he lose interest? Why is he ignoring me when he was the one telling me to keep in touch?
