Should I call my boyfriend again?

I called my boyfriend today and we said to meet in the evening. He told he'll call me later but hasn't yet so I am going out with friends and left him a message that I'm going out and if he wants to meet me around 9. He didn't reply yet. Should I call him again or let him be?
