What did I do wrong? Why is he not contacting me?

Why would he say he wants to go on a date with me as soon as possible, ask me where I wanted to go, say he liked me, kiss me on the forehead, say I was pretty, said he loved my humor, constantly hold my hand or my face, cuddle me in the morning even though he had to leave for work, but now hasn’t contacted me the last few days even though we were supposed to go on our date this week?
