New Guy already a problem

We've been texting for three days now. On the first day we texted all day long. On the second day we texted less and yesterday we only texted once( I asked what he was doing and he said laying down wbu. I responded and he didn't respond). Yesterday we were supposed to hang out and I had other plans and guys that I could have hung out with but I wanted to hang out with him. Cancelled plans with my friends thinking that he was going to come through or text and he didn't. Yet, he was the main one asking when we we were going to go out together. I asked him if I did something to him but he didn't respond. Should I just go ahead and forget him? I know he something could have happened but he could have at least texted or called me. Don't hype me up and make plans to chill on a certain day and then never text me.😒
