Why does he ignore me?

There is a guy, we've been friends for several years. He has confessed his love to me and i rejected him in a quite harsh way. Nobody ever told me *I truly love you and im in love with you* before except him. Since that day he never calls me or texts me. I called him twice and he sounded heartbroken, sent him a text a month after and he didn't even care to open it up. He used to be my support buddy, we spent much time together. he's quite good honest guy, has knowledge of most things and knows a few languages, earns above average salary. I just didn't expect such thing from him. I've been dating for years but couldnt find anyone who actually cared for me like him. Every guy I've dated with they wanted to use me. Now i see him on stories he travels and goes around, having good time with his guy and women friends. I am jealous of him. What should i do? I just pretended like nothing happened. Its been months.
