Guys: How do you feel after being dumped?

I dated someone, casually. I didn't see us go anywhere, mixed signals on his side and in the end I'm not sure myself anymore. I told him I'd love to stay friends because I sincerely care about him. I tried my best to prove I'm genuine and not avoiding to tell the truth - he completely cut me off, why? It makes me feel as though he never was that into me as he clearly doesn't care to stay friends.
